I am unable to login to my Microsoft Teams Application, getting the following error:

"Selected user account does not exist in tenant 'Microsoft Services' and cannot access the application '1fec8e78-bce4-4aaf-ab1b-5451cc387264' in that tenant. The account needs to be added as an external user in the tenant first. Please use a different account."

    Hi @Mark Berentzen

    Please kindly note that here on Microsoft Q&A forum we mainly focus on questions about Teams for Business.

    If only the personal account facing this issue, please consider posting in the corresponding Microsoft Community for better help.

    Thanks for your understanding.


    What is your account type? Please try checking the Teams web client for problems.

    Organize account:

    https://teams.microsoft.com

    Personal Account:

    https://teams.live.com/

    Are you logging in Teams via the default installed version of Teams (Teams for home or small business)?

    If you also have issues with the Teams web client, contact your admin to run the following run tests to diagnose the issue:

    1. Select the following button to populate the diagnostic in the Microsoft 365 admin center: Run Tests: Teams Sign-in
    2. In the Username or Email Address field, enter the email address of the user who's experiencing the Teams sign-in issue.

    I have an interview in 15 mins, and all I'm getting on the APP is this stupid message. I just want to login and use the application. Why isn't there any further guidance or a coded wrap around available. I have a Microsoft account, but no, today I can't use teams because of "bla bla bla" Tenant... Bla bla bla. Just fix it.
