If Microsoft Teams notifications are not appearing on your desktop, or you are missing message alerts, the problem is usually one of several notification settings — in Teams itself, in Windows, or both. Here is how to diagnose and fix each one.
1. Check Windows Notification Settings
Teams notifications go through Windows before appearing on screen. If Windows notifications are disabled for Teams, nothing will show regardless of Teams settings.
- Go to Settings → System → Notifications
- Make sure Notifications is toggled on at the top
- Scroll down to find Microsoft Teams in the app list and click it
- Ensure notifications are enabled, and check that banner, sound, and notification centre options are set as you want
2. Check Teams Notification Settings
Teams has its own notification controls independent of Windows:
- In Teams, click your profile picture (top right) and select Settings
- Click Notifications
- Review each category — Mentions, Messages, Meetings, etc. Each can be set to Banner and email, Only show in feed, or Off
- Set Chat messages and @mentions to Banner to ensure they appear on screen
3. Check Do Not Disturb and Quiet Hours
If your Teams status is set to Do Not Disturb, all notifications are suppressed except from people in your priority list. Check your status in the top-left of Teams and switch it back to Available or Busy if it is on Do Not Disturb.
Also check Windows Focus Assist (now called Do Not Disturb in Windows 11 settings): go to Settings → System → Notifications and check that Do not disturb is not turned on.
4. Check Quiet Hours in Teams
Teams has a Quiet Hours feature that mutes notifications during set times (mainly for mobile, but worth checking):
- In Teams Settings → Notifications, scroll down to Appearance and sound
- Check if Mute notifications is enabled and whether a schedule is active
5. Check Channel Notification Settings
Teams channels can be individually muted or configured for minimal notifications. If you are missing alerts from a specific channel:
- Right-click the channel name in the sidebar
- Select Channel notifications
- Set All new posts or @mentions and replies to Banner as appropriate
Channels you are not actively following will not send desktop notifications by default — only @mentions and direct replies to your messages.
6. Restart Teams
A Teams process that has been running for a long time can lose its notification connection. Right-click the Teams icon in the system tray and select Quit (not just close), then relaunch Teams from the Start menu. This clears the notification pipeline and often resolves intermittent notification failures.
7. Check for Teams Updates
Notification bugs are frequently fixed in Teams updates. Click your profile picture in Teams and select Check for updates. Teams updates automatically but can sometimes fall behind. After updating, restart Teams.
8. Clear the Teams Cache
A corrupted Teams cache can cause notification issues. Close Teams completely, then:
- Press Win + R and type
%appdata%\Microsoft\Teams - Delete the contents of the Cache, Service Worker\CacheStorage, and IndexedDB folders (leave the folders themselves)
- Relaunch Teams
Teams will rebuild its cache on next launch — this takes a minute or two.
9. Check Group Policy (Managed PCs)
On corporate-managed machines, IT policy may restrict Teams notifications. If you have tried all the above and notifications still do not work, contact your IT department — the settings may be enforced by Group Policy and cannot be changed by the end user.
