Additional chat-related features and issues within Microsoft Teams for business
Dear Killian Viamper,
Based on your description, notifications are received normally when Microsoft Teams is open, but stop working once the application is closed or minimized. This behavior is typically related to Teams not running in the background, Windows notification settings, or battery optimization restrictions.
Here are some suggestions you can try:
1/ Review Teams notification settings
- Go to Settings > Notifications and activity.
- Ensure chat notifications are set to Banner and feed.
- Verify that notification-related options are not configured to suppress alerts.
2/Check Windows notification settings
- Open Settings > System > Notifications.
- Confirm notifications are enabled globally.
- Locate Microsoft Teams in the application list and ensure notifications, banners, and notification center alerts are enabled.
3/Disable Focus Assist / Do Not Disturb
- Go to Settings > System > Notifications.
- Temporarily disable Do Not Disturb (Windows 11) or Focus Assist (Windows 10) and test again.
4/Update and refresh the Teams client
- Sign out of Teams.
- Fully quit the application from the system tray.
- Clear the Teams cache and sign back in.
- Check for updates and confirm you are running the latest version of Teams.
If the issue still persists, please try signing in to Teams on the web to see whether notifications work there. You can also try uninstalling and reinstalling the Teams app to check whether the issue persists.
