Hello folks,
I am preparing to sync my on premise AD with an Azure AD.
I have an Azure account, but have not setup in custom domains, yet.
I have an internal only local domain called copperfield.net that is not registered publicly (not available).
I use it internally for everything.
I also have an public domain called matlockinc.net, that is registered and I use for my email MX, and then forwards into my copperfield.net servers, successfully.
I can see how to register matlockinc.net in Azure custom domain, must I also create a custom domain for copperfield.net before I can sync? How would it be verified?
