Need to remove a domain from an unmaged teneacy

Hi,

For this case you may try to contact microsoft support and ask them to share details where exactly the domain is registered. Mostly any TXT or CNAME record entry register for this with any domain provider.

Hi @All IT Admin

Thank you for posting this in Microsoft Q&A.

I understand that you are trying to add a domain owned and managed by company get a message that the domain is registered in another tenancy but with no admin login account.

A self-service sign up for any cloud service that uses Microsoft Entra ID adds the user to an unmanaged or "shadow" Microsoft Entra directory and creates an unmanaged account. An unmanaged account is a directory without a global administrator. To determine whether an account is managed or unmanaged, see Determining Tenant Type.

Sometimes you can't add a domain to your organization account because someone else has already signed up for Microsoft 365 using an email address associated with that domain name. But you can remove the domain from the other, unmanaged account and add it to your organization managed account. Before you can remove the domain from the other account and add it to your account though, you must join the unmanaged account and become an admin for that account. Then, you'll remove the domain from the unmanaged account, sign back into your account, and add the domain to your managed account.

Please follow the steps which mentioned in this document to take over an unmanaged directory as administrator in Microsoft Entra ID: https://video2.skills-academy.com/en-us/entra/identity/users/domains-admin-takeover
