Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
Dear @Erica Serrao,
Thank you for posting your question in the Microsoft Q&A forum.
Based on your description, your organization owns the domain and DNS, but the Microsoft 365 tenant is controlled by a former contractor who is the only Global Administrator and is no longer employed. you wonder how Global Administrator access can be restored through Microsoft.
In this situation, since the only Global Administrator is a former contractor and no longer available, access cannot be transferred internally. The correct next step is to contact Microsoft Support and request tenant recovery through the Microsoft Data Protection Team.
There are some solutions that you can contact Microsoft Support as:
Use this link to find the appropriate contact number: Global Customer Service phone numbers - Microsoft Support
To help you navigate the automated phone system (IVR), here’s an example of how the conversation might go:
IVR: What kind of problem are you concerned about? You: Administrator account locked
IVR: What kind of product do you use? You: Office 365 for business

IVR: Are you an administrator? You: Yes
IVR: Do you have another administrator in your organization? You: No
IVR: Do you need a service request? You: Yes
This should help you get connected to a live support agent who can assist you directly.
