URGENT: Tenant Lockout – Sole Admin Blocked by MFA – Requesting Data Protection Escalation

Roberto Gallardo Flores 20

Hello,

My name is Roberto Gallardo Flores.

I am the only Global Administrator of a Microsoft 365 tenant and I am completely locked out due to MFA.

Unfortunately, I have lost access to the Microsoft Authenticator app and did not configure any backup recovery methods (no alternate phone or email).

The tenant has no other administrators, and I cannot access the Admin Portal or raise a support ticket.

This is affecting access to active business infrastructure.

I kindly request assistance from the Data Protection team to verify ownership and help restore access.

Affected admin account: ******@xxx.xxx

Thank you for your support.

Additional context:

I still have access to the phone number associated with the account and I know the password.

However, I am unable to log in because I am blocked by the Microsoft Authenticator (MFA) prompt.

Unfortunately, the recovery email is also set to the same locked account (******@xxxx.xxx), which prevents me from resetting anything.

I am fully willing to cooperate with identity verification and can provide:

My government-issued ID (DNI or passport)

Billing receipts or payment records linked to the account

Proof of domain ownership via DNS TXT records

My only request is to temporarily disable or reset MFA on the administrator account so that I can regain access to our tenant and restore business continuity.

Please let me know the next steps.

Hello @Roberto Gallardo Flores,

Thank you for sharing details over email.

The issue pertains to a tenant lockout, where no other global admin in the tenant has the necessary permissions to re-register MFA.

To resolve this, we have engaged our Data Protection team through a support ticket. They will reach out to you via email or phone to help restore access to the tenant and assist in resolving the issue.

Once the issue has been resolved by our support team, please feel free to revisit and kindly click "Accept Answer," as this will be helpful to other community members facing similar issues.
