Verifying domain name issue
We're trying to verify our custom domain in Entra ID, but it turns out the domain is already claimed on another tenant that we have no access to (unknown account, no admin credentials). Because of that, verification on our own tenant fails.
Normally the fix for a claimed-domain conflict is to open a support request so Microsoft can help release it. The problem: doing that requires a support plan, and purchasing one doesn't work for us. "payment" always succeeds and we dont get an error, but we don't get charged and the account status doesn't change, we have nothing more to go on.
So we're stuck in a loop: we need support to release the domain, but we can't buy the support plan needed to reach support.
Has anyone dealt with a domain claimed on an inaccessible tenant? And is there another route to Microsoft support when the support plan purchase itself fails?

The domain is blocked because another Entra tenant already claims it. Add the domain, publish the Microsoft TXT record, and retry verification. If Entra offers Become the admin, use the documented takeover flow. A managed tenant can externally take over an unmanaged directory through Microsoft Graph verification with forceTakeover=true, although Microsoft excludes source tenants with SharePoint, OneDrive, or Skype service plans. If the domain belongs to a managed tenant, no self-service release exists: its administrator must remove every domain reference and the domain, or Microsoft Support must verify ownership and assist. Do not keep retrying the Azure support-plan purchase. In the Entra admin center, open Diagnose and solve problems, use Self-Service Support, complete three follow-ups, and select Create a support request. Use Microsoft 365 admin center Help & support for the failed billing transaction. Include the domain, tenant ID, verification and purchase errors, timestamps, and DNS proof of ownership.
