Hello, I
I am the Global Administrator for my Microsoft 365 Business tenant for the domain PII
My admin accountPII is fully locked out due to MFA being the only available sign-in method. My Authenticator app became unlinked, and my alternate email (PII) is not receiving verification codes.
I cannot log into the admin portal, I cannot create a support ticket, and phone support routes me to an AI that requires sign-in.
I need a manual MFA reset and password reset for the global admin account. I can verify domain ownership and identity.
Please assist with unlocking the tenant.
Thank you.

Since none of the Global Administrators currently have access, this qualifies as a tenant lockout scenario. To resolve this, we will need to engage the Data Protection team by raising a support ticket to help restore your access.
To proceed, I will need a few details from you. As this information contains Personally Identifiable Information (PII), please share the following details via private message:
Contact phone number (add +Country code)
Contact email address
Global admin email address (affected account)
TenantID
Country
