Global Admin for Microsoft 365 Quit

Dear @Joshua Hahn,

Thank you for sharing your experience.

In this case, please check to see if there are other IT admins in your organization who can help you with the reset. 

If there are no other admin, in this situation, the Microsoft Data Protection team has tools and processes in place to verify identity and regain access to administrator accounts. 

Please note that as a forum moderator, I do not have access to or control over user accounts. This means I am unable to perform actions such as signing in to your account, resetting passwords, modifying account access, or viewing account-specific information. My role here is limited to providing general guidance and troubleshooting suggestions based on the shared information.

Therefore, if you are there are no other admin in your organization, then you need to involve Microsoft data protection team. They specialize in account and tenant ownership verification and can assist customers who have lost administrative access.

Once you reach out to them, the team will guide you through a verification process to confirm that the tenant belongs to your organization. After the ownership is validated, they can help you regain administrative access to the tenant.
