Sole Global Administrator locked out – case 2610191420001980 unresolved for 42 days

Sole Global Administrator locked out – case 2610191420001980 unresolved for 42 days, no mailbox access for 13 days

I am the sole Global Administrator of a Microsoft 365 Business tenant.

My MFA issue has been unresolved for 42 days under Microsoft support case 2610191420001980. I have now had no access to my business mailbox for 13 consecutive days, which is preventing me from communicating with clients and running my business.

The case has already been escalated and I have been told that the Product Group is investigating the MFA issue, but I have received no concrete information, no timeline and no solution. My case handler has also stopped responding to my emails.

I am not looking to open another support case. I need help getting the existing case reviewed and escalated internally because I currently have no access to my business email or admin account.

Could a Microsoft moderator please review this situation and contact me privately regarding case 2610191420001980?
