Hello

We lost access to the MFA device for our Global Admin account <PII REMOVED>. We still have mailbox access, but the Authenticator device is unavailable. We need an MFA reset. We are waiting for you support.

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.
