Hello,
I am locked out of my Microsoft 365 Developer tenant <Mod remove PII**>.onmicrosoft.com** due to an MFA issue.
I am the sole Global Administrator of this tenant. MFA was configured using Microsoft Authenticator on a mobile device that was replaced and reset.
I no longer have access to the original MFA device and I do not have recovery codes.
I still have access to the Microsoft 365 Developer Program dashboard with my personal Microsoft account, and the tenant is active (E5 Developer subscription).
I am requesting administrative recovery or a temporary MFA reset in order to regain access to the tenant.
Could a Microsoft support engineer please assist or escalate this case internally?
Thank you.
