My computer is running: Windows 10 Enterprise LTSC year 2018. Whenever I try to login to my company's Microsoft 365 account for use on the desktop I receive the following error:

A required authentication broker is missing. If this error keeps occurring, please contact your System Administrator.

I've gone through all of the

  1. Download Assistant and run log in error program
  2. PowerShell to reinstall the packages for Azure AD WAM plugin
  3. Uninstalled and Re-installed the software

None of that seemed to work. I just can't run office on this computer.

Any suggestions?

    The cause and fix can be complex. Are you the admin? If not, do contact your admin as you may not be the only person with the problem.

    Some random searches show others face similar problems before.

    Perhaps some of their solutions might help

    Dear Aissa,

    Please check whether you are in the Intune environment and encounter the issue.

    If yes, I suggest you post a new thread on our specific support channel Microsoft Intune Configuration - Microsoft Q&A for further help as soon as possible.

    Thanks for your effort and understanding.

    Sincerely

    Dear Tj_831,

    Based on your information with Azure AD WAM plugin and the error message, it seems that you are in an Intune environment.
