Microsoft 365 organizations that have Microsoft Defender for Office 365 included in their subscription or purchased as an add-on have Explorer (also known as Threat Explorer) or Real-time detections. These features are powerful, near real-time reporting tools that help Security Operations (SecOps) teams investigate and respond to threats.

Depending on your subscription, Threat Explorer or Real-time detections is available in the Email & collaboration section in the Microsoft Defender portal at https://security.microsoft.com:

Real-time detections is available in Defender for Office 365 Plan 1. The Real-time detections page is available directly at https://security.microsoft.com/realtimereportsv3.
Threat Explorer is available in Defender for Office 365 Plan 2. The Explorer page is available directly at https://security.microsoft.com/threatexplorerv3.

Threat Explorer contains the same information and capabilities as Real-time detections, but with the following additional features:

More views.
More property filtering options, including the option to save queries.
More actions.

For more information about the differences between Defender for Office 365 Plan 1 and Plan 2, see the Defender for Office 365 Plan 1 vs. Plan 2 cheat sheet.

The rest of this article explains the views and features that are available in Threat Explorer and Real-time detections.

Tip

For email scenarios using Threat Explorer and Real-time detections, see the following articles:

Permissions and licensing for Threat Explorer and Real-time detections

To use Explorer or Real-time detections, you need to be assigned permissions. You have the following options:

Microsoft Defender XDR Unified role based access control (RBAC) (If Email & collaboration > Defender for Office 365 permissions is Active. Affects the Defender portal only, not PowerShell):
- Read access for email and Teams message headers: Security operations/Raw data (email & collaboration)/Email & collaboration metadata (read).
- Preview and download email messages: Security operations/Raw data (email & collaboration)/Email & collaboration content (read).
- Remediate malicious email: Security operations/Security data/Email & collaboration advanced actions (manage).
Email & collaboration permissions in the Microsoft Defender portal:
- Full access: Membership in the Organization Management or Security Administrator role groups. More permissions are required to do all available actions:
  - Preview and download messages: Requires the Preview role, which is assigned only to the Data Investigator or eDiscovery Manager role groups by default. Or, you can create a new role group with the Preview role assigned, and add the users to the custom role group.
  - Move messages in and delete messages from mailboxes: Requires the Search and Purge role, which is assigned only to the Data Investigator or Organization Management role groups by default. Or, you can create a new role group with the Search and Purge role assigned, and add the users to the custom role group.
- Read-only access: Membership in the Security Reader role group.
Microsoft Entra permissions: Membership these roles gives users the required permissions and permissions for other features in Microsoft 365:
- Full access: Membership in the Global Administrator^* or Security Administrator roles.
- Search for Exchange mail flow rules (transport rules) by name in Threat Explorer: Membership in the Security Administrator or Security Reader roles.
- Read-only access: Membership in the Global Reader or Security Reader roles.
  
  Important
  
  ^* Microsoft recommends that you use roles with the fewest permissions. Using lower permissioned accounts helps improve security for your organization. Global Administrator is a highly privileged role that should be limited to emergency scenarios when you can't use an existing role.

Tip

End-user spam notifications and system generated messages aren't avaialble in Threat Explorer. These types of messages are available if there's a mail flow rule (also known as a transport rule) to override.

Audit log entries are generated when admins preview or download email messages. You can search the admin audit log by user for AdminMailAccess activity. For instructions, see Audit New Search.

To use Threat Explorer or Real-time detections, you need to be assigned a license for Defender for Office 365 (included in your subscription or an add-on license).

Threat Explorer or Real-time detections contains data for users with Defender for Office 365 licenses assigned to them.

Elements of Threat Explorer and Real-time detections

Threat Explorer and Real-time detections contain the following elements:

Views: Tabs at the top of the page that organize detections by threat. The view affects the rest of the data and options on the page.

The following table lists the available views in Threat Explorer and Real-time detections:

View	Threat Explorer	Real-time detections	Description
All email	✔		Default view for Threat Explorer. Information about all email messages sent by external users into your organization (Inbound), email messages sent by internal users in your organization to external users (Outbound), and email messages sent between internal users in your organization (Intra-org).
Malware	✔	✔	Default view for Real-time detections. Information about email messages that contain malware.
Phish	✔	✔	Information about email messages that contain phishing threats.
Campaigns	✔		Information about malicious email that Defender for Office 365 Plan 2 identified as part of a coordinated phishing or malware campaign.
Content malware	✔	✔	Information about malicious files detected by the following features: Built-in virus protection in SharePoint, OneDrive, and Microsoft Teams Safe Attachments for Sharepoint, OneDrive, and Microsoft Teams
URL clicks	✔		Information about user clicks on URLs in email messages, Teams messages, SharePoint files, and OneDrive files.

These views are described in detail in this article, including the differences between Threat Explorer and Real-time detections.

Date/time filters: By default, the view is filtered by yesterday and today. To change the date filter, select the date range, and then select Start Date and End date values up to 30 days ago.
Property filters (queries): Filter the results in the view by the available message, file, or threat properties. The available filterable properties depend on the view. Some properties are available in many views, while other properties are limited to a specific view.

The available property filters for each view are listed in this article, including the differences between Threat Explorer and Real-time detections.

For instructions to create property filters, see Property filters in Threat Explorer and Real-time detections

Threat Explorer allows you to save queries for later use as described in the Saved queries in Threat Explorer section.
Charts: Each view contains a visual, aggregate representation of the filtered or unfiltered data. You can use available pivots to organize the chart in different ways.

You can often use Export chart data to export filtered or unfiltered chart data to a CSV file.

The charts and available pivots are described in detail in this article, including the differences between Threat Explorer and Real-time detections.
Tip

To remove the chart from the page (which maximizes the size of the details area), use either of the following methods:
- Select Chart View > List View at the top of the page.
- Select Show list view between the chart and the details area.
Details area: The details area for a view typically shows a table that contains the filtered or unfiltered data. You can use the available views (tabs) to organize the data in the details area in different ways. For example, a view might contain charts, maps, or different tables.

If the details area contains a table, you can often use Export to selectively export up to 200,000 filtered or unfiltered results to a CSV file.

Tip

In the Export flyout, you can select some or all of the available properties to export. The selections are saved per user. Selections in Incognito or InPrivate browsing mode are saved until you close the web browser.

The All email view in Threat Explorer shows information about all inbound, outbound, and intra-org email messages. The view shows malicious and non-malicious email. For example:

Email identified phishing or malware.
Email identified as spam or bulk.
Email identified with no threats.

This view is the default in Threat Explorer. To open the All email view on the Explorer page in the Defender portal at https://security.microsoft.com, go to Email & collaboration > Explorer > All email tab. Or, go directly to the Explorer page using https://security.microsoft.com/threatexplorerv3, and then verify that the All email tab is selected.

Tip

¹ Latest delivery location doesn't include end-user actions on messages. For example, if the user deleted the message or moved the message to an archive or PST file.

There are scenarios where Original delivery location/Latest delivery location and/or Delivery action have the value Unknown. For example:

The message was delivered (Delivery action is Delivered), but an Inbox rule moved the message to a default folder other than the Inbox or Junk Email folder (for example, the Draft or Archive folder).
ZAP attempted to move the message after delivery, but the message wasn't found (for example, the user moved or deleted the message).

² By default, a URL search maps to http, unless another value is explicitly specified. For example:

Searching with and without the http:// prefix in URL, URL Domain, and URL Domain and Path should show the same results.
Search for the https:// prefix in URL. When no value is specified, the http:// prefix is assumed.
/ at the beginning and end of the URL path, URL Domain, URL domain and path fields is ignored.
/ at the end of the URL field is ignored.

Property filters in Threat Explorer and Real-time detections

The basic syntax of a property filter/query is:

Condition = <Filter property> <Filter operator> <Property value or values>

Multiple conditions use the following syntax:

Tip

Wildcard searches (**** or ?) aren't supported in text or integer values. The Subject property uses partial text matching, and yields results similar to a wildcard search.

The steps to create property filter/query conditions are the same in all views in Threat Explorer and Real-time detections:

Identify the filter property using the tables in the preview view description sections earlier in this article.
Select an available filter operator. The available filter operators depend on the property type as described in the following table:

Filter operator Property type

Equal any of Text
Integer
Discreet values

Equal none of Text
Discreet values

Greater than Integer

Less than Integer
Enter or select one or more property values. For text values and integers, you can enter multiple values separated by commas.

Multiple values in the property value use the OR logical operator. For example, Sender address > Equal any of > [email protected],[email protected] means Sender address > Equal any of > [email protected] OR [email protected].

After you enter or select one or more property values, the completed filter condition appears below the filter creation boxes.

Tip

For properties that require you to select one or more available values, using the property in the filter condition with all values selected has the same result as not using the property in the filter condition.
To add another condition, repeat the previous three steps.

The conditions below the filter creation boxes are separated by the logical operator that was selected at the time you created the second or subsequent conditions. The default value is AND, but you can also select OR.

The same logical operator is used between all conditions: they're all AND or they're all OR. To change the existing logical operators, select the logical operator box, and then select AND or OR.

To edit an existing condition, double-click on it to bring the selected property, filter operator, and values back into the corresponding boxes.

To remove an existing condition, select on the condition.
To apply the filter to the chart and the details table, select Refresh

Filter operator	Property type
Equal any of	Text Integer Discreet values
Equal none of	Text Discreet values
Greater than	Integer
Less than	Integer

Saved queries in Threat Explorer

Tip

Save query is part of Threat trackers and isn't available in Real-time detections. Saved queries and Threat trackers are available only in Defender for Office 365 Plan 2.

Save query isn't available in the Content malware view.

Most views in Threat Explorer allow you to save filters (queries) for later use. Saved queries are available on the Threat tracker page in the Defender portal at https://security.microsoft.com/threattrackerv2. For more information about Threat trackers, see Threat trackers in Microsoft Defender for Office 365 Plan 2.

To save queries in Threat Explorer, do the following steps:

After you create the filter/query as previously described, select Save query > Save query.
In the Save query flyout that opens, configure the following options:
- Query name: Enter a unique name for the query.
- Select one of the following options:
  - Exact dates: Select a start date and end date in the boxes. The oldest start date that you can select is 30 days before today. The newest end date that you can select is today.
  - Relative dates: Select the number of days in the Show last nn days when search is run. The default value is 7, but you can select 1 to 30.
- Track query: By default, this option isn't selected. This option affects whether the query runs automatically:
  - Track query not selected: The query is available for you to run manually in Threat Explorer. The query is saved on the Saved queries tab on the Threat tracker page with the Tracked query property value No.
  - Track query selected: The query periodically runs in the background. The query is available on the Saved queries tab on the Threat tracker page with the Tracked query property value Yes. The periodic results of the query are shown on the Tracked queries tab on the Threat tracker page.
When you're finished in the Save query flyout, select Save, and then select OK in the confirmation dialog.

On the Saved query or Tracked query tabs on the Threat tracker page in the Defender portal at https://security.microsoft.com/threattrackerv2, you can select Explore in the Actions column to open and use the query in Threat Explorer.

When you open the query by selecting Explore from the Threat tracker page, Save query as and Saved query settings are now available in Save query on the Explorer page:

If you select Save query as, the Save query flyout opens with all previously selected settings. If you make changes, select Save, and then select OK in the Success dialog, the updated query is saved as a new query on the Threat tracker page (you might need to select Refresh to see it).
If you select Saved query settings, the Saved query settings flyout opens where you can update the date and Track query settings of the existing query.
