Additional features, settings, or issues not covered by specific Microsoft Teams Free categories
Dear Lea England,
Thank you for your question and for sharing the details into Microsoft Q&A Forum.
I understand you’re seeing a red exclamation mark on the Microsoft Teams icon and would like to clear it to ensure nothing is being missed. First, please take a moment to review the AI response and the Independent Advisor’s answer in this thread as well, they include helpful checks that are worth trying. Then to help identify what Teams is flagging, could you please:
- share a screenshot showing the Teams icon with the red exclamation mark (and, if possible, the Teams window after you click the icon)?
- confirm whether you are using a Teams personal account (Microsoft account) or a work/school account?
In the meantime, please try the basic troubleshooting steps below:
- Open Teams and check for any in-app alert
- Click the Teams icon to open the app.
- Look for any banner/notification at the top (sign-in, connectivity, update prompts, etc.).
- Check Activity and Chat for any items requiring attention.
- Fully quit Teams and reopen
- Right-click the Teams icon in the system tray and select Quit.
- Open Task Manager and ensure Teams is not running (end task if it is).
- Launch Teams again from the Start menu.
- Verify sign-in status
- In Teams, click your profile picture.
- If you see any sign-in/reconnect prompt, please Sign out and then Sign in again.
- Check for updates and restart Teams
- In Teams, select Settings and more (…).
- Check for any Update option (or allow Teams to complete updates if prompted).
- Restart Teams afterward.
- Clear Teams cache
- Please follow this link to clear Teams cache: Clear the Teams cache - Microsoft Support
- Repair/Reset Teams (if still not cleared)
- Go to Settings > Apps > Installed apps.
- Select Microsoft Teams > Advanced options.
- Click Repair first.
- If the icon still shows the red exclamation mark, click Reset, then open Teams again.
I hope these steps help clear the Teams warning icon and refresh the app’s local cache successfully. Wishing you a smooth experience while Teams rebuilds the cache after restarting.
