Subject: URGENT – Sole Global Administrator locked out by MFA

Hello,

I am locked out of my Microsoft 365 Business tenant for Maison Y.

My administrator account is: [Moderator note: Personally Identifiable Information removed] @MaisonY.onmicrosoft.com

I know my password, but Microsoft Authenticator is no longer correctly registered. When I try to sign in, Microsoft only offers:

Approve a notification in Microsoft Authenticator

Enter a verification code from Microsoft Authenticator

In the Authenticator app itself, my account says I need to sign in to add the account, which sends me back to the same MFA request. I am therefore stuck in an MFA loop.

I am the only administrator / Global Administrator and there is no other admin who can reset my authentication methods.

Please escalate this to the Data Protection / Tenant Recovery team and help me reset/re-register MFA for the administrator account.

I can provide my phone number, billing details and proof of ownership if needed.

    Please note that this forum is not Microsoft support, this is a user-to-user support forum. Therefore, I cannot directly escalate this for you. However, I can guide you how to contact Data Protection team.

    Hi @Yasmine Elghali

    In this situation, you will need to contact Data Protection team. They can help you regain access to your tenant.

    Please visit the following page and reach out to phone number via: Customer service phone numbers - Microsoft Support

    From what I know, you will need to get past the initial AI system to reach the live support team. You can refer to the guide below for tips on how to get through more easily:User's image

    If you have tried phone support and it's not working, please follow this link to create a trial tenant: https://www.microsoft.com/en-us/microsoft-365/business/microsoft-365-business-basic?msockid=3eb6980b5c6860e63a588d0c5d1761d6 - after that you will be able to access to Microsoft 365 Admin Center to raise the ticket

    Assuming that you have already created an account after registering a free trial and you can go to Microsoft 365 admin center and click "Help & support" icon to raise your ticket.

    Please mention that you are raising ticket on behalf of the affected tenant that you do not have access to.

    On the other hand, if you do create the trial and it resolves the issue, please remember to cancel the subscription afterward to avoid any related charges.

    Do this steps : https://learn.microsoft.com/en-us/answers/questions/5705995/tenant-lockout-only-global-admin-lost-mfa-authenti

    1. Contact Microsoft Support and clearly state:
      • You are the only Global Administrator.
      • You know the password.
      • The issue is MFA/Authenticator lockout, not password recovery.
      • There are no alternative authentication methods and no other administrators.
      • You require tenant recovery / Global Administrator MFA reset.
    2. Request escalation for:
      • Tenant lockout
      • Global Administrator MFA recovery
      • Ownership verification and MFA reset

    Microsoft support guidance indicates that when no other administrator exists, Microsoft Support must handle the recovery after ownership verification
