Configure the expiration policy for Microsoft 365 groups

This article tells you how to manage the lifecycle of Microsoft 365 groups by setting an expiration policy for them. You can set an expiration policy only for Microsoft 365 groups in Microsoft Entra ID.

After you set a group to expire:

• Groups with user activities are automatically renewed as the expiration nears.
• Owners of the group are notified to renew the group, if the group isn't autorenewed.
• Any group that isn't renewed is deleted.
• Any Microsoft 365 group that was deleted can be restored within 30 days by the group owners or the administrator.

Currently, you can configure only one expiration policy for all Microsoft 365 groups in a Microsoft Entra organization.

Activity-based automatic renewal

With Microsoft Entra intelligence, groups are now automatically renewed based on whether they were recently used. This feature eliminates the need for manual action by group owners. It's based on user activity in groups across Microsoft 365 services like Outlook, SharePoint, Teams, or Yammer.

For example, an owner or a group member might do something like:

• Send an email to the group in Outlook.
• Upload a document to SharePoint.
• Visit a Teams channel.
• View a post in Yammer.

In the preceding scenarios, the group is automatically renewed around 35 days before the group expires and the owner doesn't get any renewal notifications.

Now consider an expiration policy that was set so that a group expires after 30 days of inactivity. To keep from sending an expiration email the day that group expiration is enabled (because there's no record activity yet), Microsoft Entra first waits five days. Then:

• If there's activity in those five days, the expiration policy works as expected.
• If there's no activity within five days, Microsoft Entra ID sends an expiration or renewal email.
• If the group was inactive for five days, an email was sent, and then the group was active, Microsoft Entra autorenews it and starts the expiration period again.

Activities that automatically renew group expiration

The following user actions cause automatic group renewal:

• SharePoint: View, edit, download, move, share, or upload files.
• Outlook: Join a group, read or write a group message from a group space, or "like" a message (in Outlook Web Access).
• Teams: Visit a Teams channel.
• Yammer: View a post within a Yammer community or an interactive email in Outlook.

Auditing and reporting

Administrators can get a list of automatically renewed groups from the activity audit logs in Microsoft Entra ID.

Roles and permissions

The following roles can configure and use expiration for Microsoft 365 groups in Microsoft Entra ID.

For more information on permissions to restore a deleted group, see Restore a deleted Microsoft 365 group in Microsoft Entra ID.

Set group expiration

1. Sign in to the Microsoft Entra admin center as at least a Groups Administrator.

2. Select Microsoft Entra ID.

3. Select Groups > All groups, and then select Expiration to open the expiration settings.

   

4. On the Expiration page, you can:

   • Set the group lifetime in days. You can select one of the preset values or a custom value. It should be 30 days or more.
   • Specify an email address where the renewal and expiration notifications are sent when a group has no owner.
   • Select which Microsoft 365 groups expire. You can set expiration for:
     • All Microsoft 365 groups.
     • Selected Microsoft 365 groups.
     • None to restrict expiration for all groups.
   • Save your settings when you're done by selecting Save.

Email notifications

If groups aren't automatically renewed, email notifications like the following example are sent to the Microsoft 365 group owners 30 days, 15 days, and 1 day prior to expiration of the group.

The groups owner's preferred language or the Microsoft Entra language setting determines the language of the email. If the group owner defined a preferred language, or multiple owners have the same preferred language, that language is used. For all other cases, the Microsoft Entra language setting is used.

From the Renew group notification email, group owners can directly access the group details page in the Access Panel. There, users can get more information about the group, such as its description, when it was last renewed, when it will expire, and also the ability to renew the group. The group details page now also includes links to the Microsoft 365 group resources so that the group owner can conveniently view the content and activity in their group.

When a group expires, the group is deleted one day after the expiration date. An email notification such as this one is sent to the Microsoft 365 group owners informing them about the expiration and subsequent deletion of their Microsoft 365 group.

You can restore the group within 30 days of its deletion by selecting Restore group or by using PowerShell cmdlets. For more information, see Restore a deleted Microsoft 365 group in Microsoft Entra ID. The 30-day group restoration period isn't customizable.

If the group you're restoring contains documents, SharePoint sites, or other persistent objects, it might take up to 24 hours to fully restore the group and its contents.

Retrieve the Microsoft 365 group expiration date

In addition to using Access Panel to view group details like expiration date and last renewed date, you can retrieve the expiration date of a Microsoft 365 group from Microsoft Graph REST API Beta. The group property expirationDateTime is enabled in Microsoft Graph Beta. You can retrieve it with a GET request. For more information, see this example.

Microsoft 365 group expiration with a mailbox on legal hold

When a group expires and is deleted, 30 days after deletion the group's data from apps like Planner, Sites, or Teams is permanently deleted. The group mailbox that's on legal hold is retained and isn't permanently deleted. The administrator can use Exchange cmdlets to restore the mailbox to fetch the data.

Microsoft 365 group expiration with a retention policy

You can configure the retention policy in the Security & Compliance portal. There you can set up a retention policy for Microsoft 365 groups. When a group expires and is deleted, the group conversations in the group mailbox and files in the group site are retained in the retention container for the specific number of days defined in the retention policy. Users won't see the group or its content after expiration. They can recover the site and mailbox data via e-discovery.

PowerShell examples

Here are examples of how you can use PowerShell cmdlets to configure the expiration settings for Microsoft 365 groups in your Microsoft Entra organization:

1. Install the Microsoft Graph PowerShell module and sign in at the PowerShell prompt.

   Install-Module Microsoft.Graph -Scope CurrentUser
   Connect-MgGraph -Scopes "Directory.ReadWrite.All"
   

2. Configure the expiration settings. Use the New-MgGroupLifecyclePolicy cmdlet to set the lifetime for all Microsoft 365 groups in the Microsoft Entra organization to 365 days. Renewal notifications for Microsoft 365 groups without owners are sent to [email protected].

   New-MgGroupLifecyclePolicy -AlternateNotificationEmails [email protected] `
      -GroupLifetimeInDays 365 -ManagedGroupTypes All
   

3. Retrieve the existing policy by using Get-MgGroupLifecyclePolicy. This cmdlet retrieves the current Microsoft 365 group expiration settings that were configured.

   Get-MgGroupLifecyclePolicy
   

   In this example, you can see:

   • The policy ID.
   • Renewal notifications for Microsoft 365 groups without owners are sent to [email protected].
   • The lifetime for all Microsoft 365 groups in the Microsoft Entra organization is set to 365 days.

   Id                                   AlternateNotificationEmails GroupLifetimeInDays ManagedGroupTypes
   --                                   --------------------------- ------------------- -----------------
   1aaaaaa1-2bb2-3cc3-4dd4-5eeeeeeeeee5 [email protected]    365                 All
   

4. Update the existing policy by using Update-MgGroupLifecyclePolicy. This cmdlet is used to update an existing policy. In the following example, the group lifetime in the existing policy is changed from 365 days to 180 days.

   Update-MgGroupLifecyclePolicy -GroupLifecyclePolicyId "1aaaaaa1-2bb2-3cc3-4dd4-5eeeeeeeeee5" -GroupLifetimeInDays 180 -AlternateNotificationEmails "[email protected]"
   

5. Add specific groups to the policy by using Add-MgGroupToLifecyclePolicy. This cmdlet adds a group to the lifecycle policy. As an example:

   Add-MgGroupToLifecyclePolicy -GroupLifecyclePolicyId "1aaaaaa1-2bb2-3cc3-4dd4-5eeeeeeeeee5" -GroupId "cffd97bd-6b91-4c4e-b553-6918a320211c"
   

6. Remove the existing policy by using Remove-MgGroupLifecyclePolicy. This cmdlet deletes the Microsoft 365 group expiration settings but requires the policy ID. This cmdlet disables expiration for Microsoft 365 groups.

   Remove-MgGroupLifecyclePolicy -GroupLifecyclePolicyId "1aaaaaa1-2bb2-3cc3-4dd4-5eeeeeeeeee5"
   

You can use the following cmdlets to configure the policy in more detail. For more information, see Microsoft Graph PowerShell documentation.

• Get-MgGroupLifecyclePolicy
• New-MgGroupLifecyclePolicy
• Remove-MgGroupLifecyclePolicy
• Update-MgGroupLifecyclePolicy
• Add-MgGroupToLifecyclePolicy
• Remove-MgGroupFromLifecyclePolicy
• Invoke-MgRenewGroup
