How can I get MS to delete a ghosted tenant on microsoft.com so that I can use my owner-verified domain name.

I am unable to add my domain to my admin account so that I can setup my e-mail addresses. Based on MS, there is a dormant or ghosted tenant that is preventing me from registering my domain name on MS.

This is the message I get from MS Admin when I try to verify my domain:

We have confirmed that you own TOFShield.com, but we can't add it to your account because the domain is already added to a different Microsoft 365 organization: graystoneeducation.onmicrosoft.com. Sign in to the admin center as an admin for that organization, and remove the domain TOFShield.com. Try resetting the admin password if you can't sign in. You should be able to add the domain TOFShield.com here after taking that step. If you can't access graystoneeducation.onmicrosoft.com, please contact our support team for help.

Please help me. Microsoft Support - the Data Protection Team is unreachable by phone and this has been going on for over 4 months.

    Please note that this forum is not Microsoft support, this is a user-to-user support forum.

    Hi @Ali EL HAMDI

    As a first step, you may want to review Admin Takeover options if the domain is associated with a dormant Microsoft 365 tenant and you can still prove ownership of the domain through DNS records. This process can sometimes allow administrators to gain control of an unmanaged or abandoned tenant and then remove or manage the domain accordingly.

    If the Admin Takeover process is not successful, the next step would be to work directly with Microsoft Support. You can contact them by phone or open a ticket via Admin Center.

    I know you have tried phone support before, please try again with the script below. Please visit the following page and reach out to phone number via: Customer service phone numbers - Microsoft Support

    From what I know, you will need to get past the initial AI system to reach the live support team. You can refer to the guide below for tips on how to get through more easily:User's image

    If you have already attempted phone support without success, and you mentioned that you have access to another Microsoft 365 tenant, you may consider opening a support ticket from that tenant's Microsoft 365 Admin Center.

    When submitting the request, please clearly explain that you are raising the support case on behalf of the affected tenant that you no longer have access to, and that the issue involves a domain that is currently tied to an inaccessible or dormant tenant. If the support team is able to help you regain administrative access to the affected tenant, you should then be able to remove the domain from that tenant. Once the domain has been removed, you can proceed with adding and verifying the domain in your current Microsoft 365 tenant.

    Important: Make sure the domain is removed from the tenant before deleting the tenant. A custom domain that remains attached to a tenant can continue to block its use in another Microsoft 365 organization until it has been properly removed.
