Azure B2C tenant lockout

Hello,

My account is the only admin in our B2C tenant and I've lost the MFA access to it. Being the only admin account we cannot reset the MFA ourselves and need assistance from Microsoft. However, the published support phone number <PII REMOVED> does not work. Can you suggest the way to approach it further?

Thanks!

    Hello Alex Lokhman

    Thanks for sharing the requested details in Private messages tab.

    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.

    I have exactly the same problem with my business account. I lost my Microsoft Authenticator access and can’t login from any computer to my OneDrive, 365 etc everything is blocked in loop.
