Hi jacombs01,
Have a great day! Welcome to our forum community. Thank you for posting. We understand how frustrating it can be to deal with technical issues, and we appreciate your patience. Based on your description, it seems you have already tried many troubleshooting steps. Could you please try the following steps based on your situation:
Is your account a user account or admin account?
For a user account, please reach out to your global admin so that they can check if your account is MFA blocked or reset your authentication settings if needed. The admin can follow the steps below:
To check for MFA blocked user, refer the steps below: Configure Microsoft Entra multifactor authentication - Microsoft Entra ID | Microsoft Learn
- Go to Protection > Multifactor authentication > Block/unblock users.
- In the Action column next to the user, select Unblock.
- Enter a comment in the Reason for unblocking box.
- Select OK to unblock the user.
To reset your authentication method please follow steps in the link attached below : Manage authentication methods for Microsoft Entra multifactor authentication - Microsoft Entra ID | Microsoft Learn
If the account is an admin account and you have multiple admins in your organization, please contact alternative admin to check for MFA blocked or reset your authentication settings using the above steps.
If you are the only admin you need to contact the Data Protection team. This team is the only support team that can verify and reset the account. To find the Data Protection team's contact number, see Customer service phone numbers - Microsoft Support
Please note that our initial response might not resolve the issue right away. However, with your cooperation and more detailed information, we can work together to find a solution if you face any challenges the steps free to let me know.
Thank you so much for your precious time and co-operation.
Sincerely,
