Summary ​

Fix Microsoft Teams notifications that aren't showing on your desktop or phone. This guide covers Teams settings, Windows notification settings, Focus Assist conflicts, and cache clearing.

Symptoms ​

  • Teams chat messages arrive but no notification banner or sound appears.
  • Meeting reminders don't pop up before meetings start.
  • Channel messages show unread counts but don't trigger notifications.
  • Notifications work in the browser but not in the desktop app (or vice versa).
  • Notification sounds are missing even though banners appear.

Prerequisites ​

  • Microsoft Teams (desktop app or mobile app).
  • Windows 11 or 10 (for desktop-specific steps).

Instructions ​

1. Check Teams Notification Settings ​

Make sure Teams is configured to send notifications.

  1. Open Microsoft Teams and click the three-dot menu (⋯) next to your profile picture.
  2. Select Settings > Notifications and activity.
  3. Under Notifications, verify that Chat, Meetings, and Other are not set to Off.
    • Set critical ones to Banner and feed or Banner, feed, and email.
  4. Scroll down and check that channel notifications for important channels are set to All activity or Custom.

TIP

If you only want notifications for channels you care about, right-click the channel name in the Teams sidebar, select Channel notifications, and choose All activity. This is more effective than turning on notifications for every channel.

2. Check Your Teams Status ​

Your status directly affects whether notifications are delivered.

  1. Click your profile picture in Teams.
  2. Check your status. If it's set to Do Not Disturb, all notifications are silenced.
  3. Change your status to Available or Busy (Busy still delivers notifications with a visual indicator).
  4. If you set a status duration, clear it by selecting Reset status.

3. Check Windows Notification Settings ​

Windows may be blocking Teams notifications at the system level.

  1. Press Windows + I to open Settings.
  2. Go to System > Notifications.
  3. Make sure the master Notifications toggle is On.
  4. Scroll down to the app list and find Microsoft Teams.
  5. Click it and verify:
    • Notifications is turned On.
    • Show notification banners is checked.
    • Play a sound when a notification arrives is checked.

4. Check Focus Assist / Do Not Disturb ​

Windows Focus Assist silences all notifications — including Teams.

  1. Click the clock or battery icon in the taskbar to open Quick Settings.
  2. Look for Focus or Do not disturb. If it's enabled, click it to turn it off.
  3. To keep Focus Assist on but allow Teams through, go to Settings > System > Focus and add Teams to priority notifications.

WARNING

Focus Assist can turn on automatically during certain times (like presentations or when duplicating your display). Go to Settings > System > Focus > Automatic rules to review and adjust these triggers.

5. Clear the Teams Cache ​

A corrupted cache can break notifications silently.

  1. Close Microsoft Teams completely (right-click the Teams icon in the system tray and select Quit).
  2. Press Windows + R, type %appdata%\Microsoft\Teams, and press Enter.
    • For new Teams, type %localappdata%\Packages\MSTeams_8wekyb3d8bbwe\LocalCache\Microsoft\MSTeams instead.
  3. Delete all contents inside the folder.
  4. Restart Teams and sign back in.

Teams rebuilds its cache. Check if notifications are working.

6. Verify the Fix ​

Confirm notifications are working.

  1. Ask a colleague to send you a Teams chat message.
  2. You will see a desktop notification banner and hear a sound.
  3. If notifications appear, the fix worked.

Troubleshooting ​

WARNING

If you're using both the desktop app and Teams in a browser tab, notifications may only appear in whichever client is currently active. Close the browser tab if you want all notifications to go through the desktop app.
