Couldn't sign into my enterprise account.

That worked for me aswell, delete folder:

%localappdata%\Package\Microsoft.AAD.BrokerPlugin_cw5n1h2txyewy

on the user with the problem.

But I had to do it as a local admin, and then find the problem user Microsoft.AAD.BrokerPlugin_cw5n1h2txyewy folder.

The most effective fix for office licensing that I have found:

Logout of:

                Word

                Teams

                OneDrive

                Edge

Credential manager:

                Delete all Windows Credentials.

Registry:

                Delete:

                HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\Common\Identity

Files to remove:

      Delete the Licenses and Licensing folders at:

      %localappdata%\Microsoft\Office\Licenses

      %localappdata%\Microsoft\Office\16.0\Licensing

Reboot.

Give the computer a minute at boot.

      Teams should automatically start.

      Logon to it first.

      Wait 30+ Seconds. Continue to chat with our client.

Open OneDrive

      Sign in. Use the current folder.

      Wait another 30+ seconds while OneDrive syncs

            Chat with our client.  They don’t bite. :O)

Open Edge

      Logon to Office online

            I use portal.office.com

            Sign them in and then use the Waffle

            Open Word and open a blank document.

            Choose to edit it in the Desktop App.

            As it opens the Desktop app it should

            Ask you to activate office and succeed in

            Licensing it.  There are a couple of cases

            Where I had to do this twice.  The first time

            It said it updated office and to close out of

            Word/Office.  Closed and tried again and it worked.

This method has been super reliable for me. 99% of the time.

Any suggestions or other methods you have found to work?
