We have an instance of Azure Active Directory services that was created when we setup our Office365 instance using a domain we assigned (for example contoso.com). We would like to add Active Directory Domain Services to this instance so that we can join servers created in Azure to the domain. Is it best practice to create the Domain Services instance under a subdomain (for example aadds.contoso.com), or better to just create it under the root domain (contoso.com)?
Thanks in advance for any advice.
