Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
Dear @Shel Kumar,
Welcome to Microsoft Q&A.
Thank you for sharing the details of your situation.
It’s also important to clarify the scope of this forum. This is a user‑to‑user support forum, and nobody here has access to your tenant, admin accounts, or billing systems. As moderators and community members, we don’t have the ability to reset admin access, cancel subscriptions, or make backend changes on your behalf.
If you are trying to remember or identify the original admin account, you may want to check:
The email inbox that was used when the tenant was first created (welcome or setup confirmation emails often include the admin sign‑in address).
Any billing or invoice emails related to the subscription, which are typically sent to the Global or Billing Admin.
Any device where Office apps were previously activated, as the signed‑in account may still be visible in the app’s account information.
However, if you’re unable to identify or sign in with that account, there is no self‑service method to recover it.
In this scenario, the only supported and secure path forward is to contact Microsoft Support and request assistance from the Microsoft Data Protection Team. This team has the required tools and security procedures to verify ownership of the tenant, and either restore administrative access or help stop the subscription billing if access cannot be recovered.
To move forward, please contact Microsoft Support directly and request assistance from the Data Protection team.
Please try to find the related hotline number to call the frontline let them raise a ticket for you: Customer service phone numbers - Microsoft Support
In some countries, this is an automated conversation: First, when you call the hotline, they will ask you what kind of problem you are struggling with.

A: What products do you use?
B: Office 365 for business.
Verification: Education or company account?
B: For companies
A: Are you an administrator?
B: Yes.
A: Are there any other administrators in your organization?
B: No.
A: I need one.... Service request?
B: Yes
If your organization's Office 365 Business/Education subscription is from a partner or reseller, and the global administrator is unable to open a service request on your end, contact the reseller's support provider to help open a service request on behalf of you instead.
If you still cannot reach to agent, there is still a workaround, you might consider registering for a new tenant by signing up for a trial subscription via this link Compare All Microsoft 365 Plans | Microsoft. This would allow you to create a new tenant following the provided prompts. Once set up, you can access the admin console of the new tenant and submit a support ticket requesting to speak with the Data Protection team on behalf of your previous tenant.
Please remember to cancel the trial subscription once your issue is resolved to avoid any unintended charges.
I understand that this entire process can feel long and complicated, and I truly appreciate your patience while working through it. These steps are in place to protect the security of your account, so I hope you can understand why they are required. I sincerely hope you’ll be able to regain access to your account soon. If you need help at any point, or if you have any questions during the process, please feel free to reach out, I’m always here and happy to assist.
Thank you again for your understanding and patience.
