Issue: O365 may produce an error ‘Create Contact failed. Please enter a unique email address for the Contact.’ when you create a contact that does not exist in the ‘Contacts’ window.

Solution: You have this user listed as a ‘Guest’ in AzureAD. You CAN have a Guest and Contact match, but you have to create the Contact FIRST and then invite them to AzureAD afterward, in that exact order. Delete the Azure invite and rerun it by doing the Contact in O365 user management first.
