Immediate Escalation Request – Sole Global Admin Locked Out, Existing Case Unresponsive (Case #2608030010002111)

Question

I am the sole Global Administrator for my Microsoft 365 business tenant (honuplanning.com) and have been completely locked out of my account for over a month.

What happened: My Microsoft Authenticator app stopped working. I deleted and reinstalled the app to try to fix it, which removed the locally stored credential for this work account. Because work/school accounts aren't cloud-backed-up by Authenticator, I can no longer re-register it — and re-registering requires being signed in, which I can't do. There is no other admin on this tenant and no working alternate verification method available at sign-in.

Current status: I opened a support case (ID 2608030010002111), which was assigned to Adithya on the Data Protection team. He sent one message saying he'd follow up with a call, but I have not heard anything since, despite replying with an urgent follow-up.

What I need: This is my only business account and I've been locked out of my email and files for over a 24 hours. I'm asking for this case to be escalated and for someone from the Data Protection/Tenant Recovery team to contact me directly as soon as possible to verify my identity and restore access.

I have proof of domain ownership (honuplanning.com) and business ownership documentation ready to provide.

Thank you for any help getting this moving.
