Teams app is stuck on 'loading' on Mac

Hey all,

Might as well rebooting after uninstall and re-install,

that works for me

Removed all the microsoft cache (from keychain), logged in on teams web, created a meeting and joined via link, then clicked on "open app".

Worked like a charm,

I ran into the same issue this morning. It appears to be a problem with login / authentication. It's as if the user session for the Teams desktop app has expired, thus the app can not log itself in to join a meeting. But for some reason instead of showing a login widget, the app instead gets stuck in an infinite "loading..." state.

Reinstalling the app won't fix this problem. You need to clear the preferences and the application cache. Here's what worked for me:

1. Quit the teams app or force quit if needed.
2. In your account's Library directory, remove both the ~/Library/Application Support/Teams AND the ~/Library/Caches/com.microsoft.teams folders. This should completely reset your login state.
3. Finally, restart Teams and you should now be able to login and join meetings again.

This problem is, frankly, absurd. I'm sure that the Microsoft developers could fix it. They just don't care. Instead the company hires know-nothing level 1 support staff to fill these threads with useless tips like "upgrade your OS" or "try an antivirus scan". It's pathetic.
