Office 365 Education service description

Microsoft Office 365 is available in a variety of plans to best meet the needs of your organization. If you're looking for the differences between the Office 365 education plans, this article will show you which features are included in each of them. Office 365 combines the familiar Microsoft Office desktop suite with cloud-based versions of Microsoft's next-generation communications and collaboration services—including Microsoft Exchange Online, Microsoft SharePoint Online, Microsoft 365 for the web, and Teams for Education—to help users be productive from virtually anywhere through the internet.

This article lists the features for Office 365 education plans (A1, A3, and A5). To compare features across business and enterprise plans, see Compare Office 365 for Business plans or, for a more detailed list of features, see the relevant service description under Microsoft 365 and Office 365 service descriptions.

Microsoft Purview compliance portal features

The Microsoft Purview compliance portal is designed to help you manage compliance features across Office 365 for your organization. Links to existing SharePoint and Exchange compliance features bring together compliance capabilities across Office 365. Currently, many of the compliance features are still accessible through service-specific management interfaces, such as the Exchange admin center (EAC). However, this will change in the future as more service-independent compliance features are added to the Microsoft Purview compliance portal.

Feature Office 365 A1 Office 365 A3 Office 365 A5
Access to the Microsoft Purview compliance portal, Threat management (such as mail filtering and anti-malware), Mobile device management, Microsoft Purview Data Loss Prevention for email and files, Data governance1, Content search, Manual retention/deletion policies, Unified auditing6 Yes Yes Yes

Note

1Data governance lets users create, publish, and manually apply labels to documents; import data using drive shipping or over the network; and create and apply retention/deletion policies across workloads, users, and groups. Retention policies applied to mailboxes require Office 365 Enterprise E3 or E5.
2 Advanced data governance allows you to retain important information and delete unimportant information by classifying information based on a retention or deletion policy or both. It includes intelligent/automated actions such as recommending policies; automatically applying labels to data; applying labels based on sensitive data types or queries; and use of smart import filters. It also includes the Supervision feature for reviewing employee communications for security and compliance purposes.
3 Up to 1.5 TB of archive storage space.
4 eDiscovery (Premium) is supported in the United States and in the Western Europe (Netherlands) region. Customer data from Canada and Asia Pacific is exported to the United States. Customer data from Europe, the Middle East, and Africa is exported to Western Europe (Netherlands).

Note

1 Windows Server AD RMS is an on-premises server that must be purchased and managed separately in order to enable the supported IRM features.
2 Transport rules are made up of flexible criteria, which allow you to define conditions and exceptions, and actions to take based on the criteria. The available criteria and actions differ between Exchange Online, and Microsoft Exchange Server 2013. For a list of available criteria and actions, see the corresponding criteria and actions topics for each product.
3 Exchange Server 2013 uses only the Microsoft anti-malware engine. Exchange Online uses multiple anti-malware engines to scan inbound, outbound, and internal messages for malware.
4 SharePoint Online must be included in the subscription plan.
5 Connected accounts are supported for POP and IMAP accounts, but disabled for Outlook.com (Hotmail).
6 Using a cmdlet to work with the Address List and Global Address List is not supported.
7 Some third-party web parts and add-ins may not be available.
8 For eDiscovery, you need a separate query for on-premises vs. cloud.
9 Table indicates whether the client works with the associated plans. It does not mean the clients are necessarily included in the purchase of these plans.

Exchange Online limits

Find the Exchange Online limits for a variety of service areas, including address book limits, mailbox storage limits, and reporting and message trace limits, to name just a few.

Note

If you need assistance with a task or if you are troubleshooting a problem, you might find the following articles helpful:

The limits in Microsoft Exchange Online fall into one of the following categories:

Important

  • The limits applied to a Microsoft 365 organization may differ depending on how long the organization has been enrolled in the service. When a limit is changed in the Microsoft data centers, it can take some time to apply the change to all existing customers.
  • You can't modify most of these limits, but you and your users should be aware of them.
  • These limits apply to both internal and external recipients.
  • By default, Exchange Online Protection (EOP) protects Exchange Online mailboxes. For limits that apply to EOP features in Exchange Online, see Exchange Online Protection limits.
  • For information about Office 365 group limits, see "How do I manage my groups?" in Learn about Office 365 groups.

Address book limits

  • Address list limit - The maximum number of address lists that can be created in an Exchange Online or Exchange Server 2013 organization. This number includes the default address lists in Exchange Online, such as All Contacts and All Groups.

  • Offline address book limit - The maximum number of offline address books (OAB) that can be created in an Exchange Online or Exchange Server 2013 organization.

  • Address book policies limit - The maximum number of address book policies (ABP) that be created in an Exchange Online or Exchange Server 2013 organization.

  • Global address lists - The maximum number of global address lists (GAL) that be created in an Exchange Online or Exchange Server 2013 organization.

Feature Office 365 A1 Office 365 A3 Office 365 A5
Address list limit 1000 1000 1000
Offline address book (OAB) limit, Address book policies (ABP) limit, Global address lists limit 250 250 250

Mailbox storage limits

The amount of mailbox storage available is determined by the mailbox type and the user's subscription license. Administrators can reduce maximum mailbox sizes per user or globally.

Note

Using journaling, transport rules, or auto-forwarding rules to copy messages to an Exchange Online mailbox for the purposes of archiving is not permitted. A user's archive mailbox is intended for just that user. Microsoft reserves the right to deny additional archive storage space in instances where a user's archive mailbox is used to store archive data for other users or in other cases of inappropriate use.

Feature Office 365 A1 8 Office 365 A3 Office 365 A5
User mailboxes 50 GB 100 GB 100 GB

Site mailboxes4 50 GB 50 GB 50 GB
Public folder mailboxes 50 GB5 50 GB5 100 GB5
Group mailboxes 50 GB 50 GB 50 GB

Note

1 Each user initially receives 100 GB of storage in the archive mailbox. When auto-expanding archiving is turned on, additional storage is automatically added when the 100 GB storage capacity is reached. Additional storage space is added incrementally until the archive storage capacity reaches 1.5 TB. For more information, see Overview of auto-expanding archiving. See the Office 365 Roadmap for details about availability.
2 To access a shared mailbox, a user must have an Exchange Online license. Shared mailboxes don't require a separate license. However, if you want to enable In-Place Archive or put an In-Place Hold or a Litigation Hold on a shared mailbox, then an Exchange Online Plan 2 license or an Exchange Online Plan 1 with Exchange Online Archiving license is required. If you enable In-Place Archive and auto-expanding archiving for a shared mailbox, additional storage is automatically added when the 100 GB storage capacity for the archive mailbox is reached.
3 Resource mailboxes don't require a license.
4 Site mailboxes are created and managed in SharePoint Online. For more information, see Prepare for using site mailboxes in Office 365.
5 You are limited to 1000 public folder mailboxes, and the maximum total size of all public folder mailboxes is 50 TB.
6 In-Place Archive can only be used to archive mail for a single user or entity (such as a shared mailbox) for which a license has been applied. Using an In-Place Archive as a means of storing mail from multiple users or entities is prohibited. For example, an IT administrator can't create a shared mailbox and have users copy it (through the Cc or Bcc field, or through a transport rule) for the explicit purpose of archiving. Note that a shared mailbox that multiple people use does not actually store email for those individual users. Multiple users have access, and they send email as the shared mailbox. Therefore, the only emails stored in the shared mailbox are those sent to or from it, as the shared mailbox.
7 If you have created a retention policy in Exchange Online, messages will be automatically moved to a user's archive mailbox only if the user's primary mailbox is larger than 10 MB. The retention policy will not run automatically for mailboxes that are smaller than 10 MB.
8 Each user initially receives 50 GB of storage in the archive mailbox. If auto-expanding archiving is turned on, additional storage is automatically added when the 50 GB storage capacity is reached. Additional storage space is added incrementally until the archive storage capacity reaches 1.5 TB. For more information, see Overview of auto-expanding archiving. See the Office 365 Roadmap for details about availability.

Capacity alerts

Exchange Online provides three kinds of notifications when a user's mailbox is nearing, or at, capacity:

  • Warning - The user receives an email warning that the mailbox is approaching the maximum size limit. This warning is intended to encourage users to delete unwanted mail.

  • Prohibit Send - The user receives a prohibit-send notification email when the mailbox size limit is reached. The user cannot send new messages until enough email is deleted to bring the mailbox below the size limit.

  • Prohibit Send/Receive - Exchange Online rejects any incoming mail when the mailbox size limit is reached, and sends a non-delivery report (NDR) to the sender. The sender has the option to try resending the mail later. To receive messages again, the user must delete email until the mailbox is below the size limit.

Feature Office 365 A1 Office 365 A3 Office 365 A5
Warning 49 GB 98 GB 98 GB
Prohibit Send 49.5 GB 99 GB 99 GB
Prohibit Send/Receive 50 GB 100 GB 100 GB

Mailbox folder limits

These limits are intended to limit mailboxes to known dimensions that can be supported in Exchange Online. The goal of these limits is to prevent an infinite number of mailbox items per folder, an infinite number of folders per mailbox, or an infinite number of public folders per Exchange Online organization. For practical purposes, mailbox folder limits are in effect unlimited and sufficient to support most Exchange Online mailboxes and on-premises mailboxes that are migrated to Exchange Online.

  • Maximum number of messages per mailbox folder - Specifies the maximum number of messages for a mailbox folder. New messages can't be delivered or saved in a folder when this limit is reached.

  • Warning for number of messages per mailbox folder - Specifies the number of messages that a mailbox folder can hold before Exchange Online sends a warning message to the mailbox owner. When this quota is reached, warning messages are sent once a day.

  • Maximum number of messages per folder in the Recoverable Items folder - Specifies the maximum number of messages that can be contained in each folder in the Recoverable Items folder. When a folder exceeds this limit, it can't store new messages. For example, if the Deletions folder in the Recoverable Items folder has exceeded the message count limit and the mailbox owner attempts to permanently delete items from their mailbox, the deletion will fail.

  • Warning for number of messages per folder in the Recoverable Items folder - Specifies the number of messages that each folder in the Recoverable Items folder can hold before Exchange Online logs an event to the application event log.

  • Maximum number of subfolders per mailbox folder - Specifies the maximum number of subfolders that can be created in a mailbox folder. The mailbox owner won't be able to create a new subfolder when this limit is reached.

  • Warning for number of subfolders per mailbox folder - Specifies the number of subfolders that can be created in a mailbox folder before Exchange Online sends a warning message to the mailbox owner. When this quota is reached, warning messages are sent once a day.

  • Maximum folder hierarchy depth - Specifies the maximum number of levels in the folder hierarchy of a mailbox. The mailbox owner won't be able to create another level in the folder hierarchy of the mailbox folder when this limit is reached.

  • Warning for folder hierarchy depth - Specifies the number of levels in the folder hierarchy of a mailbox folder that can be created before Exchange Online sends a warning message to the mailbox owner. When this quota is reached, warning messages are sent once a day.

  • Maximum number of public folders - Specifies the maximum number of public folders in the complete public folder hierarchy. When this limit is reached, existing public folders must be deleted before new public folders can be created.

  • Maximum number of subfolders per public folder - Specifies the maximum number of subfolders that can be created in a public folder. New subfolders can't be created in a public folder when this limit is reached.

  • Warning for number of subfolders per public folder - Specifies the number of subfolders that can be created in a public folder before Exchange Online sends a warning message to the folder owner. If no owner exists, warning messages are sent to users with Owner permissions. When this quota is reached, warning messages are sent once a day.

Note

1 This is the storage quota for the Recoverable Items folder, not the quota for the entire archive mailbox. The storage quota for the archive mailbox is 1.5 TB for users with an Exchange Online Plan 2 license or for users who have both an Exchange Online Plan 1 and an Exchange Online Archiving license. For information about increasing the Recoverable Items quota, see Increase the Recoverable Items quota for mailboxes on hold.
2 The initial storage quota for the Recoverable Items folder in an archive mailbox is 50GB for Office 365 A1 and 100 GB for Office 365 A3/A5. When auto-expanding archiving is enabled, additional storage is automatically added when the storage capacity for the Recoverable Items folder is reached. For more information, see Overview of auto-expanding archiving. See the Microsoft 365 Roadmap for details about availability of auto-expanding archiving.

Message limits

  • Message size limit - Message size limits are necessary to prevent large messages from blocking delivery of other messages and affecting service performance for all users. These limits include attachments, and apply organization-wide to all messages (inbound, outbound, and internal). Messages larger than this limit will not be delivered, and the sender will receive a non-delivery report (NDR). While message size limits can be configured up, down, or on a per-user basis, administrators can also create transport rules to limit the maximum size of any individual attachment. To learn more, see Microsoft supports larger email messages.

    Note

    Some email clients may have lower message size limits or may limit the size of an individual file attachment to a value that is less than the Exchange Online message size limit.

  • Subject length limit - The maximum number of text characters allowed in the subject line of an email message.

  • File attachments limit - The maximum number of file attachments allowed in an email message. Even if the total size of all the file attachments doesn't violate the message size limit, there is still a limit on how many attachments are allowed in the message. This limit is controlled by the multipart message limit.

  • File attachment size limit - The maximum file size of a single attachment.

    Note

    This is the maximum file size of a single attachment. Individual client programs, including Outlook on the web, may limit the size of attachments below this maximum. Exchange ActiveSync does not implement attachment size limits on an individual attachment basis. The total size of all attachments to an Exchange ActiveSync message must be less than the message size limit.

  • Multipart message limit - The maximum number of message body parts that are allowed in a MIME multipart message. This limit also controls the maximum number of file attachments that are allowed in a message.

  • Embedded message depth limit - The maximum number of forwarded email messages that are allowed in an email message.

1 Microsoft administrators can specify a custom limit between 1 MB and 150 MB. However, the size of message you can send or receive also depends on what your email client or solution supports. For more information about customizing the maximum allowed message size for your organization, see Microsoft supports larger email messages.
2 You can send and receive up to 150 MB messages between users (where the message never leaves the Microsoft datacenters). Messages that are routed outside of the Microsoft datacenters are subject to an additional 33% translation encoding increase, in which case the maximum message size is 112 MB.
3 OWA accounts for the possibility that your message may be subject to the 33% encoding increase and restricts the size of message you can send to 25% less than the configured setting. For example, if you customize your settings for a 100 MB maximum message size, you can send messages no larger than 75 MB.
4 The size of messages to be moved into Exchange Online are computed by Exchange Online. Versions of Exchange prior to Exchange Server 2013 may report a smaller item size. This limit applies to move based migrations using any supported Exchange Mailbox Replication Service. Other migration methods (Cutover, Staged, IMAP, PST) and other third-party tools are limited by the general message size limit.

Receiving and sending limits

Receiving and sending limits are applied to combat spam and mass-mailing worms or viruses. These limits help to protect the health of our systems and keep our users safe.

Receiving limits

Receiving limits apply to the number of messages that a user, group, or public folder can receive per hour. This applies for both messages received from the Internet and from on-premises servers. When the receiving limit has been exceeded, any emails sent to that mailbox will receive a non-delivery report stating that the mailbox has exceeded the maximum delivery threshold. After one hour, the limit will refresh and the mailbox will once again be able to receive messages.

Feature Office 365 A1 / A3 / A5
Messages received 3600 messages per hour

Sending limits

Sending limits apply to the number of recipients, number of messages, and number of recipients per message that a user can send from their Exchange Online account.

Note

For distribution groups stored in an organization's address book, the group is counted as one recipient. For distribution groups stored in the Contacts folder of a mailbox, the members of the group are counted individually.

  • Recipient rate limit - To discourage the delivery of unsolicited bulk messages, Exchange Online has recipient limits that prevent users and applications from sending large volumes of email. These limits are applied per-user to all outbound and internal messages.

    Note

    Exchange Online customers who need to send legitimate bulk commercial email (for example, customer newsletters) should use third-party providers that specialize in these services.

  • Recipient limit - This is the maximum number of recipients allowed in the To:, Cc:, and Bcc: fields for a single email message.

    Note

    For the purposes of the recipient rate limit and the recipient limit, a distribution group that is stored in the organization's shared address book counts as one recipient. In a personal distribution list, each recipient is counted separately.

  • Message rate limit - Message rate limits determine how many messages a user can send from their Exchange Online account within a specified period of time. This limit helps prevent overconsumption of system resources by a single sender. If a user submits messages at a rate that exceeds the limit via SMTP client submission, the messages will be rejected and the client will need to retry.

Feature Office 365 A1 / A3 / A5
Recipient rate limit 10,000 recipients per day
Recipient limit 500 recipients
Recipient proxy address limit 400
Message rate limit (SMTP client submission only) 30 messages per minute

Reporting and message trace limits

For reporting and message trace limits, see the "Reporting and message trace data availability and latency" section in Reporting and message trace in Exchange Online Protection.

Retention limits

These limits control the length of time that items in specific folders in the Inbox can be accessed.

  • Deleted Items folder retention period - The maximum number of days that items can remain in the Deleted Items folder before they're automatically removed.

  • Retention period for items removed from the Deleted Items folder - The maximum numbers of days that items removed from the Deleted Items folder are retained before they're permanently deleted.

  • Junk Email folder retention period - The maximum number of days that items can remain in the Junk Email folder before they're automatically removed.

Feature Office 365 A1 / A3 / A5
Deleted Items folder retention period No limit1
Retention period for items removed from the Deleted Items folder 14 days1
Junk Email folder retention period 30 days

Note

1 This is the default limit. Administrators can change this value for their organization.

Distribution group limits

These limits apply to distribution groups in your organization's shared address book.

  • Maximum number of distribution group members - The total recipient count is determined after distribution group expansion.

  • Limit sending messages to large distribution groups - Distribution groups that contain the number of members specified by this limit must have delivery management or message approval options configured. Delivery management specifies a list of senders who are allowed to send messages to the distribution group. Message approval specifies one or more moderators who must approve all messages sent to the distribution group.

  • Maximum message size for large distribution groups - If a message is sent to 5,000 or more recipients, the message size can't exceed this limit. If the message size exceeds the limit, the message isn't delivered, and the sender receives a non-delivery report (NDR). The total recipient count is determined after distribution group expansion.

Feature Office 365 A1 / A3 / A5
Maximum number of distribution group members1 100,000 members
Limit sending messages to large distribution group 5,000 or more members
Maximum message size for large distribution groups 2 MB
Maximum number of distribution group owners 10
Maximum number of groups a user can create 300,0002

Note

1 If you are using Microsoft Entra DirSync, the maximum number of distribution group members that you can synchronize from your on-premises Active Directory to Microsoft Entra ID is 15,000. If you are using Microsoft Entra Connect, that number is 50,000.
2 This limit also applies to admins.

Journal, transport, and inbox rule limits

The following list includes limits that apply to journal rules, transport rules (also known as organization-wide rules), and limits that apply to Inbox rules. Inbox rules are set up by individual users and applied to messages sent and received by the individual user's mailbox.

  • Maximum number of journal rules - The maximum number of journal rules that can exist in the organization.

  • Maximum number of transport rules - The maximum number of rules that can exist in the organization.

  • Maximum size of an individual transport rule - The maximum number of characters that can be used in a single transport rule. The characters are used in the conditions, exceptions, and actions.

  • Character limit for all regular expressions used in all transport rules - The total number of characters used by all the regular expressions in all the transport rule conditions and exceptions in the organization. You can have a few rules that use long and complex regular expressions, or you can have many rules that use simple regular expressions.

  • Scanning limits for attachment content - The transport rule conditions let you examine the content of message attachments, but only the first 1 MB of the text extracted from an attachment is inspected. This 1 MB limit refers to the text extracted from the attachment, not to the file size of the attachment. For example, a 2 MB file may contain less than 1 MB of text, so all of the text would be inspected.

  • Maximum number of recipients added to a message by all transport rules - When a message is acted on by different transport rules, only a finite number of recipients can be added to the message. After the limit is reached, any remaining recipients aren't added to the message. Also, distribution groups can't be added to a message by a transport rule.

  • Forwardee limit - The maximum number of recipients that can be configured for an inbox or transport rule with a redirecting action. If a rule is configured to redirect a message to more than this number of recipients, the rule won't be applied and any message that satisfies the rule condition won't be redirected to any of the recipients listed in the rule.

  • Number of times a message is redirected - The number of times a message will be redirected, forwarded, or replied to automatically based on Inbox rules. For example, User A has an Inbox rule that redirects messages to User B, based on the sender. User B has an Inbox rule that forwards messages to User C based on keywords in the subject line. If a message satisfies both of these conditions, the message is only sent to User B; it's not forwarded to User C because only one redirection is allowed. In this case, the message is dropped without sending a non-delivery report (NDR) to User B indicating that the message wasn't delivered to User C.

Feature Office 365 A1 / A3 / A5
Maximum number of journal rules 50 rules
Maximum number of transport rules 300 rules
Maximum size of an individual transport rule 8 KB
Character limit for all regular expressions used in all transport rules 20 KB
Scanning limits for content of attachments 1 MB
Maximum number of recipients added to a message by all transport rules 100 recipients
Forwardee limit 10 recipients
Number of times a message is redirected 1 redirection

Moderation limits

These limits control the moderation settings that are used for message approval applied to distribution groups and transport rules.

  • Maximum size of the arbitration mailbox - If the arbitration mailbox exceeds this limit, messages that require moderation are returned to the sender in a non-delivery report (NDR).

  • Maximum number of moderators - The maximum number of moderators that you can assign to a single moderated distribution group or that can be added to a message using a single transport rule. Note that you can't specify a distribution group as a moderator.

  • Expiration for messages waiting for moderation - By default, a message waiting for moderation expires after two days. However, the processing of expired moderated messages runs every seven days. This means that a moderated message can expire at any time between two and nine days.

  • Maximum rate for expired moderation notification messages - This limit sets the maximum number of notification messages for expired moderated messages in a one-hour period. This limit is placed on each mailbox database in the datacenter.

    During periods of heavy usage, some senders may not receive notification messages for moderated messages that have expired. However, these notifications are still discoverable using delivery reports.

Feature Office 365 A1 / A3 / A5
Maximum size of the arbitration mailbox 10 GB
Maximum number of moderators 10 moderators
Expiration for messages waiting for moderation 2 days
Maximum rate for expired moderation notification messages 300 expiration notifications per hour

Exchange ActiveSync limits

The following limits apply to Microsoft Exchange ActiveSync, a client protocol that synchronizes mailbox data between mobile devices and Exchange.

  • Exchange ActiveSync device limit - The maximum number of Exchange ActiveSync devices per mailbox.

  • Exchange ActiveSync device deletion limit - The maximum number of Exchange ActiveSync devices that an Exchange administrator can delete in a single month.

  • Exchange ActiveSync file attachment limit - The maximum size of a message file attachment that can be sent or received by an Exchange ActiveSync device.

Feature Office 365 A1 / A3 / A5
Exchange ActiveSync device limit 100
Exchange ActiveSync device deletion limit 20
Exchange ActiveSync file attachment limit 25 MB

Education Pooled Storage limits

Microsoft 365 Education tenants will have a tenant level pooled storage limit which measures and limits the total storage provided and consumed across OneDrive, SharePoint Online, and Exchange Online. Beginning at a school’s next contract renewal, but no sooner than August 1, 2024, all school tenants will receive 100TB of free pooled storage across OneDrive, SharePoint, and Exchange, with an additional pooled storage added on a per paid user basis (not including Student Use Benefits). See below for a full list of paid subscriptions and storage contributions.

What is pooled storage?

Pooled Storage for Education provides a single pool of storage for each tenant which spans OneDrive, SharePoint Online, and Exchange Online. The storage pool represents the maximum amount of storage collectively for these 3 services and is shared across and consumed by all users within the tenant. All SharePoint Sites contribute towards pooled storage. All OneDrives contribute towards pooled storage. In Exchange Online, pooled storage contributions include User Mailboxes, Shared Mailboxes, and Group Mailboxes. All other mailbox types, including Archive mailboxes, do not count towards pooled storage.

Who will receive the pooled storage limit?

If your tenant has assigned a majority of (greater than 50%) EDU licenses compared to non-EDU licenses, or if your tenant has purchased more EDU licenses than non-EDU licenses, the tenant will be managed as an EDU tenant and will be subject to Education Pooled Storage. The pooled storage limit is in addition to other various service level and user level limits specified within this service description documentation.

How is pooled storage calculated?

All Education tenants with Pooled Storage are granted an initial and free 100 TB of storage to their pool. Additionally, each paid license which includes storage will add a specific quantity of storage to the pool. Finally, customers may purchase additional storage-only licenses in 10TB increments to add to their pool.

Pooled Storage Capacity = Default Storage Pool (100 TB) + Paid License Contributions + Storage License Contributions

For example, each purchased Microsoft 365 A3 for Faculty license will contribute an additional 50 GB to the centralized storage pool, and each purchased Microsoft 365 A5 for Faculty license will contribute an additional 100 GB to the centralized pool. If a tenant contains 1,000 paid Microsoft 365 A3 for Faculty licenses, and 1,000 paid Microsoft 365 A5 for Faculty licenses, the tenant storage total calculation would be:

  • Default limit = 100 TB (102,400 GB) of pooled storage
  • 1,000 Microsoft 365 A3 for Faculty = 50,000 GB of pooled storage
  • 1,000 Microsoft 365 A5 for Faculty = 100,000 GB of pooled storage

102,400 GB (Default) + 50,000 GB (A3) + 100,000 GB (A5) = 252,400 GB Pooled Storage capacity

This is a summary view of pooled storage Paid License Contributions by license type.

For a comprehensive list of paid license contributions, which include both Education and Commercial licenses, download the full list of license contributions here.

The storage pool contributions for a license do not have any specific or direct impact on the individual user who has the license assigned. For example, a Microsoft 365 A3 for Faculty license will contribute 50GB to the pool, however, the user with this license assigned may continue to consume from the pool based on the OneDrive user level limit set by the IT admin. The IT admin may have set the user’s OneDrive limit to 100 GB or 1 TB, well beyond the license’s pooled storage contribution amount. The 50 GB contribution only affects the central storage pool, not the individual user.
