Hi @AVOS CORP
Welcome to Q&A forum ~
As the "Access work or school" is the option of Windows system, I would add back the tag "windows-server". Thanks for your understanding.
From the Office perspective, it is recommended to remove related identities under the Identities registry entry.
Computer\HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\Common\Identity\Identities
(Please note, serious problems might occur if you modify the registry incorrectly. Before you modify it, please remember to back up the registry for restoration in case problems occur.)
Then you could go to Credential Manager > Windows credentials, remove the credentials associated with this account.
Hope the information could be helpful.
