Microsoft Teams Classic - keep crashing when joining meeting (error: 211)

Copper Contributor

I have Microsoft Teams Classic installed on my Mac (Personal Profile).


When I am trying to connect to a meeting, I get redirected to the web browser with the message:

Choose web session og Desktop session


When pressing "Desktop Session" it redirects me back to the Teams app - and error message says "Could you please log in again? We apologize for the occasion." Error 211.


Already tried:

Uninstall and reinstall - still not working

Clearing all cache - still not working

Called Microsoft customer support - still not working


Let me know if you need more information from me!

FYI - the web version is working fine! But the desktop is not working at all...


Thank you in advance!

@SS-3TV I would strongly advice to go to the new teams client!
