Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
Hello @Mehak Fatima,
Thank you for posting your valuable question on Microsoft Q&A forum.
To release and detach your domain from an existing Microsoft 365 tenant, the domain must first be removed from the tenant where it is currently registered. Microsoft requires administrative access to complete these steps, and without access to the old tenant, removal cannot be done from your side.
Since you no longer have administrative access to that tenant, the next step is to contact Microsoft’s Data Protection / Account Recovery team and request tenant admin account recovery. You can also ask for assistance in removing the domain when you reach out to a support engineer.
Please carefully follow this instruction to ask for Microsoft Data Protection team support:
Find the related hotline number to call the frontline and let them raise a ticket for you: Customer service phone numbers - Microsoft Support
Depending on your country or region. For some countries, when calling the support number, although there are about 30 seconds opening as something "you can visit the link...." But you can ignore this opening and wait until the option, then "1" as a business email user, "1" again for technical help.
For some countries, it will be an automated conversation like:
First, when you call the hotline, it asks what kind of problem you are worried about.
Answered: authenticator.
A: What kind of product are you using?
B: Office 365 for business.
A confirmation: education or company account?
B: For companies
A: Are you an administrator?
B: Yes.
A: Do you have the other admin in your organization?
B: No.
A: You need one.... Service request?
B: Yes
If your subscription is from a partner or reseller, contact the reseller's support provider to help open a service request on behalf of you instead.
After your access is restored, you can follow Microsoft’s domain‑removal instructions to detach the domain from the old tenant. These steps are documented in Microsoft’s guidance for removing a domain, which explains that all users, groups, and aliases using the domain must be moved to another domain before removal is allowed: Remove a Domain from Microsoft 365 - Microsoft 365 admin | Microsoft Learn
Once the domain is fully removed from the old tenant, you’ll be able to:
- Add it to your new Microsoft 365 setup through GoDaddy or Microsoft 365 directly.
- Close the old tenant if you no longer need it: Close your Microsoft business account | Microsoft Learn
