URGENT: Sole Global Administrator Locked Out for 3+ Weeks — Domain Ownership Verified, No Resolution or Escalation Available

I am the sole Global Administrator of my company's Microsoft 365 tenant and have been completely locked out of my account for over three weeks after replacing my iPhone and losing access to Microsoft Authenticator.

Despite completing every verification step requested by Microsoft's Data Protection Team, I have been unable to regain access to my business email, administrative account, or essential business systems.

I have an existing Microsoft Data Protection support case and can provide the case number, tenant information, and supporting correspondence privately to an authorized Microsoft moderator.

Timeline of Events

October 20: Initiated the account recovery process after losing access to Microsoft Authenticator. As the sole Global Administrator, I have no other administrator who can reset my authentication methods.

November 3: Microsoft requested that I verify ownership of my three business domains by adding specific DNS TXT records. I completed the requested changes.

November 6: Confirmed that the required DNS TXT records were publicly visible for all three domains.

November 9: A Microsoft 365 Data Protection Support Engineer explicitly confirmed in writing that ownership verification had been successfully completed for all three domains. The engineer stated that the case would be submitted for expedited approval and that I would receive an update during business hours.

November 10–12: Despite repeated follow-ups and requests for escalation, I have received no substantive update, callback, or explanation of what is preventing restoration of access.

Attempts to Escalate

I have repeatedly requested escalation to a supervisor, a direct callback, and an explanation of the outstanding steps necessary to reset my MFA registration.

I also contacted Microsoft's business support telephone number, but the automated system would not connect me with a human representative. Instead, it instructed me to reply to my existing support email thread.

The problem is that repeated emails to the Data Protection Team have not resulted in any substantive response or resolution.

I am effectively trapped in a support process where:

I cannot access my Microsoft 365 administrative account or business email.

I cannot reset my own MFA because I am the sole Global Administrator.

Microsoft has already confirmed ownership of my domains, but access has not been restored.

Telephone support redirects me to an email thread that is not producing a resolution.

My repeated requests for a supervisor or escalation manager have gone unanswered.

The continued loss of access is materially affecting my ability to operate my business and may have resulted in financial losses.

Assistance Requested

I am asking whether a Microsoft moderator or support escalation manager can help with the following:

Review and escalate my existing Data Protection case to a supervisor or senior engineer responsible for administrator account recovery.

Confirm whether the approval referenced by the support engineer on November 9 was submitted and what its current status is.

Determine whether any additional verification or authorization is outstanding, given that Microsoft has already confirmed my domain ownership.

Help establish direct communication with someone authorized to reset my Microsoft Entra ID authentication methods so I can re-register Microsoft Authenticator.

Provide a clear next action and responsible point of contact so this issue can be resolved.

I am not requesting standard MFA troubleshooting instructions. I have already exhausted the available recovery options and completed Microsoft's requested identity and domain ownership verification.

At this point, I need help getting my existing case reviewed and acted upon by the appropriate Microsoft team.

Could a Microsoft moderator please initiate a private message with me? I can securely provide my existing support case number, tenant details, domain verification evidence, and relevant correspondence.

I would greatly appreciate assistance in escalating this matter and restoring access to my business systems.
