URGENT: Sole Azure Global Administrator MFA Lockout — Microsoft Support Verification Fails, Unable to Open Support Case

Hello Microsoft Support Team and Microsoft Learn Moderators,

I am requesting assistance identifying a way to reach Microsoft's authorized tenant recovery team. I have exhausted the normal support channels and cannot open a support case.

Background

I am the sole Global Administrator of an active Microsoft Azure/Entra ID tenant with a Pay-As-You-Go subscription.

After replacing my iPhone and wiping the previous device, I lost the ability to complete the Microsoft Authenticator MFA process when accessing the Azure Portal.

The first authentication approval succeeds, but a second MFA challenge never reaches my new phone.

My administrator account is a personal Microsoft account represented in Entra ID as an external (#EXT#) user.

Verified technical findings

My existing authenticated Azure CLI session still works. Using Microsoft Graph, I have confirmed that:

• My account is assigned the built-in Global Administrator role.

I am the only Global Administrator in the tenant.

Azure Resource Manager and Microsoft Graph remain accessible.

My current Graph token lacks the delegated permissions required to manage authentication methods or directory role assignments.

Microsoft support channels attempted

Azure Portal: Cannot complete MFA to access the support interface.

Azure Support REST API: Ticket creation failed with InvalidSupportPlan.

Microsoft telephone support: The automated system directed me to visualsupport.microsoft.com.

Administrator verification: Both my original Microsoft account address and Entra external UPN were rejected with the message: "Our records indicate that you may not be a Global Administrator on this account."

Microsoft 365 support: I created a temporary tenant solely to reach support, but its billing account remains Under Review and the Admin Center offers only an automated telephone route.

Azure paid support: I am willing to purchase a support plan, but the purchase process fails with an account/tenant authentication error before I can complete the transaction.

Why this is urgent

My laptop is experiencing multiple unexpected restarts daily and requires an Intune rebuild.

The existing Azure CLI session is currently my only verified administrative access to the original tenant. Rebuilding the laptop could eliminate that access.

The tenant contains active Terraform-managed infrastructure, Azure Container Apps, GitHub Actions runners, and remote Terraform state. I do not want to delete, migrate, or recreate these resources.

Assistance requested

Could a Microsoft staff moderator or authorized support representative please identify a verified way to initiate a support case for this situation?

I specifically need:

Manual verification of my Global Administrator role and tenant ownership.

Assistance reaching Microsoft's Data Protection or Tenant Recovery team.

Recovery of my existing MFA registration on my replacement iPhone.

A support channel that does not require the same MFA authentication or automated administrator verification that is currently failing.

I am willing to pay for the appropriate Microsoft support plan or a legitimate recovery engagement.

I can provide tenant identifiers, Microsoft Graph role-assignment evidence, billing details, and proof of ownership privately through an official Microsoft support channel.

Please do not redirect me to the standard Azure Portal support workflow or automated telephone verification process. Both have already been attempted repeatedly and are inaccessible.

Thank you for your assistance.

Regards, Randolph W. StephensonHello
