Hello Peter992385 

 

If ever the problem persists, you can try this solution that I found on a blog :

I was having problems authenticating the Teams app on Mac Os with Catalina.

Best,

    Uninstalling Team, removing Registry keys and two folders related to Teams (identified in the Registry) then re-installing after a computer restart seems to have resolved the Windows login problem as well.

     

    Should not have to do this type of thing to get software working!

    Thanks! Alexversak65 

     

    Your suggestion fixed the problem on the Mac. I had actually already tried most of the steps. The one I had not tried was restarting with the 'command-option-p-r' that does a reset to the Mac's NVRAM, PRAM, and SMC. That seemed to correct the issue.

     

    Now all I need to do is get it working on Windows... I wonder if something is in the Registry - I will poke around and see if I can uninstall then delete any remaining registry keys and see what happens.

     

    Thanks again
