    Thanks for posting here in the Microsoft Community. I understand you are experiencing Outlook Error 401, which is an authentication failure that occurs when the mail server rejects your saved or entered credentials. To help isolate the issue, could you please let us know if you are using a personal account such as @outlook.com or @gmail.com or a business domain? Additionally, have you already tried verifying your password on a web browser or clearing your saved credentials via the Windows Credential Manager?
