Does that domain have email address, then possibly, a viral tenant. In such a case, you can use steps mentioned here - https://learn.microsoft.com/en-us/azure/active-directory/users-groups-roles/domains-admin-takeover
Can't use my custom domain (Seems like someone else is using it without my permission)
Hello,
I started an Azure account this week and start learning about the services. By the time I tried to use my domain as a custom domain, it says is already configured on another subscription I didn't recognize.
I own the domain, and I am the only owner so there is no way it could be used it in a legit way within a subscription...
The domain name belongs to my personal branch so I'm very worried about someone else using it!
I raise an Azure chat, but they address me to here.
Hope you can help me,
Regards,
