A cloud-based identity and access management service for securing user authentication and resource access
A forced domain release from a managed Microsoft Entra tenant that is not under administrative control is not supported in the provided material.
The available guidance only covers:
- Adding a custom domain to a tenant and verifying it via DNS TXT/MX records.
- Common verification issues, including the case where a domain is already verified in another directory and must be deleted from that original directory before it can be verified in a new one.
- Taking over unmanaged (viral) tenants, such as those created by self-service sign-up (for example, Power BI), via the “take over an unmanaged directory” process.
From the context:
- A domain name can only be verified in one directory at a time. If it is already verified in another directory, it cannot be verified in a new directory until it is removed from the original directory.
- The documented remediation for duplication is: delete the domain name from the old directory, then verify it in the new directory.
- For unmanaged tenants created by self-service sign-up, there is a documented admin takeover process. This does not apply to managed tenants.
Because the current tenant holding the domain is a managed tenant that is not under administrative control, and there is no documented forced-release or forced-takeover mechanism for such tenants in the provided content, no supported technical steps can be given beyond what is already described: the domain must be removed from the original tenant before it can be added and verified in another.
