Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
Dear Michael,
I'm sorry to hear you're locked out of your only Global Administrator account. That sounds stressful, especially since you've already tried every route you have. Unfortunately, as a forum moderator, I am not able to escalate cases to the Data Protection team or set up a support channel for you. My role here is limited to providing general guidance you can apply from your side.
You're the only admin and SSPR can't finish, so the Data Protection team is the only team that can confirm you own the tenant and get you back in. Phone support is still the main way to reach them. I understand that you have already attempted to contact Support by phone without success. You may consider contacting Support again using the phone numbers listed in the article below and following the script below to help navigate the automated phone system and reach the appropriate support team more effectively.
Customer service phone numbers - Microsoft Support
IVR: What kind of problem do you have?
You: Account recovery
IVR: What kind of product do you use?
You: Office 365 for business.
IVR confirmation: education or business account?
You: For Business
IVR: Are you an administrator?
You: Yes.
IVR: Is there another administrator in your organization?
You: No.
IVR: Do you need a... service request?
You: Yes, please connect me with the Data Protection team.
Kindly note that you may need to repeat this process a few times, availability can vary based on local business hours, and the term "Global Admin" should be clearly mentioned during the call.
I hope you get through soon and regain access to your tenant. Wishing you all the best.
