We setup an Azure tenant so that we can use Azure Active Directory to login to enterprise applications such as Adobe Creative Cloud with an enterprise ID. When our users login to Adobe CC using their enterprise ID (domain account) they login with their full email address "user@contoso.com". We also have a second domain (not AD) that we own ("domain.com") and it is used only as an smtp address in Exchange for a few employees to use for correspondence with consultants.
Is it possible to use the smtp address domain.com to login to Adobe CC by creating a upn in AD domains and trusts that matches domain.com. This way Bob whose email address is bob@contoso.com (domain account) could use his smtp address bob@domain.com. Would Azure Active Directory be able to search and find that address if we attempted to add it as an assigned user?
Any help would be greatly appreciated. Thank you.
Jose
