In my default directory within Azure Active Directory, I have multiple domains that are registered and verified. When I try to delete a specific one, I get a very unhelpful error message,"Could not delete domain 'mydomainname.co.uk'. Please try again. If the problem persists, contact support."
The domain is unused, and there are no users that use the domain. Can anyone offer any advice on what to try? It seems ridiculous to have to create a paid-for support subscription to overcome a problem with the Azure interface... :-/
