Configure alert notifications in Microsoft 365 Defender
- Microsoft 365 Defender
- Microsoft Defender for Endpoint Plan 1
- Microsoft Defender for Endpoint Plan 2
- Microsoft Defender for Business
You can configure Microsoft 365 Defender to send email notifications to specified recipients for new alerts. This feature enables you to identify a group of individuals who will immediately be informed and can act on alerts based on their severity.
If you're using Defender for Business, you can set up email notifications for specific users (not roles or groups).
- Only users with 'Manage security settings' permissions can configure email notifications. If you've chosen to use basic permissions management, users with Security Administrator or Global Administrator roles can configure email notifications.
- Device group creation is supported in Defender for Endpoint Plan 1 and Plan 2.
You can set the alert severity levels that trigger notifications. You can also add or remove recipients of the email notification. New recipients get notified about alerts triggered after they're added. For more information about alerts, see View and organize the Alerts queue.
If you're using role-based access control (RBAC), recipients will only receive notifications based on the device groups that were configured in the notification rule. Users with the proper permission can only create, edit, or delete notifications that are limited to their device group management scope. Only users assigned to the Global administrator role can manage notification rules that are configured for all device groups.
The email notification includes basic information about the alert and a link to the portal where you can do further investigation.
Create rules for alert notifications
You can create rules that determine the devices and alert severities to send email notifications for and the notification recipients.
Go to Microsoft 365 Defender and sign in using an account with the Security administrator or Global administrator role assigned.
In the navigation pane, select Settings > Endpoints > General > Email notifications.
Click Add item.

This information might be processed by recipient mail servers that are not in the geographic location you have selected for your Defender data.
