    RobertWPBI had the same problem on W10. Ran teams in compatibility mode as W7 and worked on first try.

How about trying to login as the previous username on the desktop. What happens then?

Username was update on AD updating MS 365 to new username, adding the previous email to new username also. I am not able to log into MS 365 using previous username.

    Hi,

     

    Attempted those changes this morning, still unsuccessful.

    I ended up deleting my .OST mail data file and I am now not able to open any MS Office client product. Ups. 🙂 

    New error to my bucket. I have not been able to replicate .OST file even after running the MS Office 365 Support and Recovery Assistant repair tool.

    as always brother, thanks for your suggestions.

    Thanks.

    Ok, going to take one last swing at it before a ticket

    In Windows go to Settings (Cog) > Accounts > Email and Accounts. Are there any there that shouldn't be there (I.e. one with your old username? Or, another corporate user If so, remove them, only your account with it's current username ought to be there, alongside any personal accounts

    Now my co worker is having the same error after I logged out of his Teams client. he is also not able to log in. It seems that my profile might have been leaving some trace making the Teams client not able to load. Will you know if there might be a location that the application might pull information from other than the previously suggested?

    This is a tough one

    I would raise a ticket to support with screenshots and the steps attempted

    1.) Removed and Reinstalled
    2.) Cleared cache
    3.) Cleared credential manager
    4.) Date and time are fine on machine
    5.) Logged in and out of Office Apps

    In addition to the other info - changed on AAD, works on web/mobile app. My feeling is that it is a modern auth issue, or the network - do you have conditional access? Can you log in outside the corporate network?

    Best, Chris
