Microsoft 365 Developer Program E5 Tenant Locked Out - Sole Global Administrator Lost Microsoft Authenticator Access

Hello Microsoft Team,

We need urgent assistance recovering access to our Microsoft 365 Developer Program E5 tenant.

Tenant Information

Tenant Name: xw76x.onmicrosoft.com

Affected Global Administrator:

[Moderator note: Personally Identifiable Information removed]@xw76x.onmicrosoft.com

Issue Summary

The account above is the only Global Administrator in our tenant.

The Microsoft Authenticator app that was registered for MFA is no longer accessible. Because of this, we cannot complete Multi-Factor Authentication during sign-in.

We know the account password, but sign-in is blocked because approval from the Microsoft Authenticator app is required.

Current Impact

We are completely locked out of administrative management and cannot:

• Add new team members
• Remove users who have left the organization
• Assign or remove licenses
• Manage Microsoft Teams
• Manage Microsoft Entra ID settings
• Access Microsoft 365 Admin Center

Additional Information

• Tenant has been active for approximately 4 years more and we are still on the program.
• This is a Microsoft 365 Developer Program E5 tenant.
• There are no other Global Administrators available.
• Associated Microsoft account: [Moderator note: Personally Identifiable Information removed]@gmail.com
• We can provide additional verification information if required.

Request

We would appreciate guidance on the recovery process for a Developer Program tenant where the sole Global Administrator has lost access to the registered Microsoft Authenticator app.

Can Microsoft assist with:

1. Verifying ownership of the tenant
2. Resetting MFA/authentication methods for the Global Administrator account
3. Restoring administrative access to the tenant

Thank you.
