Using classic Outlook for Windows in business environments
Hi Bill,
I am Mario and I am a independent advisor, and I would like to help you.
Go to https://account.microsoft.com, on the "Security" tab in the "Additional Security Options" section click on "Microsoft Authenticator App" click on "Remove".
Hope this can help you solving the issue.
Is there anything else I can help you with?
Best regards,
Mário
