Each step is explained clearly, so even if you are not very tech-savvy, you can follow along without trouble.
By the end, you will understand why this happens and how to stop old messages from appearing repeatedly.
Quick Note
Before starting, make sure your Microsoft Teams app is updated to the latest version. Updates often fix bugs that cause issues like old messages popping up.
Also, check your internet connection. A poor connection can cause syncing problems, leading to repeated message notifications.
Finally, confirm that your Windows 11 system is updated. System updates improve app compatibility and performance.
Step 1: Restart Microsoft Teams
Sometimes, simply restarting Teams can clear temporary glitches.
- Close Microsoft Teams completely. To do this, right-click the Teams icon in the system tray (bottom-right corner) and select Quit.
- Wait for a few seconds to ensure it is fully closed.
- Open Microsoft Teams again from the Start menu or desktop shortcut.
This step refreshes the app and can fix minor issues causing old messages to pop up.
Step 2: Clear Teams Cache
Teams stores data in a cache to load faster, but sometimes this cache gets corrupted. Clearing it can fix display or notification problems.
Here is how to clear the cache on Windows 11:
- Close Microsoft Teams completely (use the Quit option from the system tray).
- Press
Win + Rto open the Run dialog box. - Type
%appdata%MicrosoftTeamsand press Enter. - In the folder that opens, delete all the files and folders inside. This will clear the cache.
- Restart Microsoft Teams.
Clearing the cache forces Teams to fetch fresh data from the server, which often resolves old message notifications.
Step 3: Check Notification Settings
Incorrect notification settings may cause repeated alerts for old messages.
- Open Microsoft Teams.
- Click your profile picture in the top-right corner and select Settings.
- Go to the Notifications tab.
- Review your notification preferences, especially for Chat and Mentions.
- Adjust settings to your preference, for example, set notifications to Only show in feed or Banner and feed.
Updating notification settings helps Teams manage how and when you receive alerts, reducing repeated pop-ups.
Step 4: Sign Out and Sign Back In
Sometimes, re-authenticating your account can solve syncing and notification problems.
- In Teams, click your profile picture and select Sign out.
- Close the app after signing out.
- Open Teams and sign back in using your credentials.
This refreshes your account connection and resolves many background sync issues causing old message alerts.
Step 5: Update Microsoft Teams
Running an outdated version of Teams can cause unexpected bugs.
- Open Teams.
- Click on your profile picture in the top-right.
- Select Check for updates.
- Teams will automatically check and install any available updates.
- Restart the app after updating.
Keeping Teams updated ensures that known issues are patched, improving overall performance and notification accuracy.
Step 6: Reinstall Microsoft Teams
If the problem persists, reinstalling Teams can fix corrupted files.
- Press
Win + Ito open Settings. - Go to Apps > Installed apps.
- Find Microsoft Teams in the list.
- Click the three dots next to it and select Uninstall.
- After uninstalling, visit the official Microsoft Teams download page and install the latest version.
Reinstalling ensures you have a fresh, clean copy of the app without leftover corrupted data.
Alternative Method: Use the Web Version of Teams
If the desktop app continues showing old messages, try using the web version at teams.microsoft.com.
The web app does not rely on local cache and often avoids these notification glitches.
