Hi kent Elford
Thank you for reaching out to the Microsoft Q&A forum.
I understand how frustrating it can be when you're trying to sign in to your work account in Outlook and the process fails due to issues with the Microsoft Authenticator app. I'm here to help you through it.
First, could you please confirm you can still sign in to your account using alternative methods such as phone, SMS or an alternate method?
If your account has other alternate sign in methods:
When you're prompted for a code in the Microsoft Authenticator app, look for a small link that says something like “I don’t have a code” or “Use a different verification option.” This option should let you choose an alternative method to verify your identity.
If your account does not have other alternate sign in methods:
Since this is a work account, the best approach is to reach out to your organization’s IT team. They can reset your multi-factor authentication settings, allowing you to re-register the Microsoft Authenticator app. For guidance: Manage authentication methods - Microsoft Entra ID | Microsoft Learn. Please note that, as moderators, we do not have administrative access to make these changes.
If you are the sole Global Administrator and find yourself completely locked out of the tenant:
You may need to reach out to us via our customer service phone number: Customer service phone numbers - Microsoft Support. An agent will be able to create a ticket for you under the affected tenant and then escalate this ticket to the Data Protection team, who can assist you in regaining access.
I hope this helps clarify your situation and guides you toward regaining access to your accounts. If you encounter any issues or have further questions, please don't hesitate to reply to my answer with any updates.
