It will however work to let me login to my family account thats still active. I have no way of getting into my business account for ******@domain.com. I cannot get ahold of anyone at microsoft customer support which is insane. so i have to post a Q&A to get help. What a disgrace Microsoft.

    Hello @Elijah Willis,

    Thank you for sharing the details over email.

    The issue relates to a tenant lockout situation where no other global admin in the tenant has the necessary admin rights to re-register MFA.

    To resolve this, we engaged our Data Protection team through a support ticket. Please connect with our support team via the ticket, and they will assist you in resolving the issue.

    I hope this information is helpful. Please feel free to reach out if you have any further questions.
