Couldn't sign into my enterprise account.

The second part was the solution for me. ONLY removing the account from the "Access work or school" settings in Windows and reconnected all accounts resolved the issue.

Changing office or registry settings had NO effect.

This was the solution that worked for me, so frustrating as it should be the FIRST thing to try as it does not require editing the registry, clearing TPM or anything else destructive.

HELLO, I CAN'T VERFY MY MICROSOFT ACCOUNT WHAT SHOULD I DO?

Doing this has fixed all of ours. There is one more thing that helps. Click on Windows key. start typing to bring up search. In that search, top right you will see your account. Verify your account there. That is the last thing that helps. But the below has been necessary for tough cases.

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.

The one more thing is to verify our account in Windows search listed at the top of this post.

Any suggestions or other methods you have found to work?
