I have an existing Azure Active Directory instance that was created when we created our Office365 account. I would now like to add Active Directory Domain Services so that we can add some virtual machines and add them to this domain. Is it advisable to create Active Directory Domain Services against the custom DNS namespace being used for our current instance, or is it advisable to create a subdomain to this existing domain space?

    Hello,

    please find below the guidelines for picking a DNS domain name.

    In addition, keep in mind that you can have only one Azure AD DS per Azure AD tenant and it could currently exist in only one Azure region.
