Single Global Administrator in tenant PIIis stuck in MFA registration loop

Question

Tenant lockout scenario. Single Global Administrator in tenant PII is stuck in MFA registration loop due to authentication methods limit reached. No other GA available. Need emergency reset of authentication methods

Answer 1

Hello Robert Nowak

The issue pertains to a tenant lockout, where no other global admin in the tenant has the necessary permissions to login and make changes in your tenant.

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.

Answer 2

I have already attempted that scenario.

When I try to contact Microsoft Data Protection Support by phone, the automated system continuously redirects me to the online support page. The issue is that I cannot sign in to that page because the only Global Administrator account in the tenant is stuck in the MFA registration loop.

As a result, I am unable to reach a human support agent, and the automated system keeps routing me back to the same sign-in page, which I cannot access.

Could you please escalate this case directly to the Data Protection / Tenant Recovery team or provide a direct contact method that does not require signing into the affected tenant?
