- Product
- Microsoft Teams and Viva Engage
- Device & OS
- not provided
- Scenario
- Monitoring Viva Engage community updates and mentions directly within the Microsoft Teams application.
- Observed behavior
- Notifications do not display in the Activity feed despite correct user notification configurations and testing across multiple Teams versions.
Ensure that your Microsoft Teams application is updated to the latest version and verify that your personal notification settings for Viva Engage are toggled on in the Teams settings menu.
Enable the Enforce Office 365 Identity Setting
This organizational setting must be enabled for Viva Engage (Yammer) profiles to sync properly with Microsoft 365, which allows notifications to route to the Teams activity feed.
Viva Engage relies on the underlying Microsoft 365 identity infrastructure to deliver cross-app notifications. If the legacy Yammer identity configuration is still active, Teams will not receive activity feed triggers.
Have your Microsoft 365 Global Admin or Yammer Network Admin log in to the Yammer/Viva Engage admin center.
In the left-hand navigation pane, go to Network Admin and click on Security Settings.
Locate the 'Enforce Office 365 identity in Yammer' section, check the box to enable it, and save your changes.

Open a Microsoft 365 Support Ticket
If the Office 365 identity enforcement is already active but notifications are still missing, Microsoft engineers must investigate the backend synchronization logs.

Frequently Asked Questions
Why did Viva Engage replace Yammer notifications?
Microsoft rebranded Yammer as Viva Engage to better integrate community experiences, employee communications, and knowledge sharing directly into Microsoft 365 and Microsoft Teams. The notification infrastructure remains connected to the same backend.
How do I check my personal Viva Engage notification settings in Teams?
In Microsoft Teams, click the three dots (...) next to your profile picture at the top right, select Settings, and go to Notifications. Scroll down to the Viva Engage section to ensure your activity feed notifications are turned on.
Can an individual user fix the 'Enforce Office 365 Identity' setting?
No. This is a tenant-wide security setting that governs how user identities are authenticated across the organization. It can only be modified by a Microsoft 365 Global Administrator or a Yammer Network Administrator.
