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,
