MFA locked out of M365 Business tenant – only Global Admin – need Data Protection reset (Tracking ID #[Moderator note: Personally Identifiable Information removed])

I am the sole Global Administrator on a Microsoft 365 Business tenant and have been locked out for 6 days due to an MFA issue. The authenticator is requiring a code I cannot receive. I have an open support ticket (Tracking ID [Moderator note: Personally Identifiable Information removed]) but have been unable to reach a live agent — the phone support line loops to AI only, and the admin center is inaccessible because I cannot complete MFA to sign in.

I need the Data Protection team to verify my identity and reset MFA on this account. As the only Global Admin, there is no secondary admin who can reset this for me from inside the tenant.

Steps already tried:

  • Microsoft account recovery page (does not apply to business/work accounts)
  • Phone support at 1-800-642-7676 (AI only, no human option)
  • Web-based reset flow (requires MFA to complete)

I completed identity verification with a Microsoft support agent on Wednesday June 24, 2026. The agent confirmed my MFA would be reset overnight and that I would receive a callback on Thursday June 25 to confirm. As of today, Friday June 27, neither has happened — MFA is still active, my account is still inaccessible, and no one has called.

  • Tracking ID: [Moderator note: Personally Identifiable Information removed]  
  • Account: [Moderator note: Personally Identifiable Information removed]  
  • Tenant domain: oecexperts.com

I need to know:

  1. What is the status of the reset committed by the agent on June 24?
  2. Why was the promised callback not made on June 25?
  3. How do I escalate this to someone who can complete the reset today?

This is now Day 6 of a complete business lockout. I cannot access email, calendar, or any M365 service.

Please escalate urgently.

    Hi @Heather O'Shea,

    I’m really sorry to hear about the situation you’re facing.

    Based on the tracking ID you provided, I’ve made an effort to reach out to the relevant team to help request further review and follow-up on your case. I’ve also just sent you a private message here. To access it, please click the banner notification shown in the image below:

    As a forum moderator, I completely understand how urgent this situation is. However, I also hope you can understand that I don’t have the ability to directly intervene in tenant recovery scenarios or make changes to account security settings such as MFA resets. Those actions are strictly handled by Microsoft’s internal support teams, particularly the Data Protection team.

    What I can do is support you within my scope by helping to check the current status of your support case, provide clarity on where things may stand, and guide you on the next best steps to help move this forward as quickly as possible.

    I truly hope this helps in some way, and I’ll do my best to continue supporting you through this. Please reply to the private message when you have a moment, and we can follow up from there.

    Looking forward to hearing from you.
