Is Microsoft Teams down?

Before you change settings, check Microsoft 365 Service health. If there's an outage, wait it out.

How to fix it: step by step

Check whether Teams is down for everyone: look at status.cloud.microsoft or Microsoft 365 Status on X and recent posts from the service's official status account before changing anything on your device.
Fully quit Teams (right-click the taskbar/menu bar icon > Quit), then reopen it.
Try Teams on the web at teams.microsoft.com. If it works there, the problem is local.
Clear the cache for new Teams on Windows: Settings > Apps > Installed apps > Microsoft Teams > Advanced options > Reset. (Your chats are stored in the cloud.)
Sign out, restart your computer, and sign back in.
Update Windows/macOS and reinstall Teams if needed.

FAQ

Will resetting Teams delete my chats?

No. Chats and files are stored in Microsoft 365, not in the local cache.
