Setup UPN Suffix

UPN suffix setup is important to sync the users from on prem AD to Azure AD. We need to create UPN suffix according to your Azure AD UPN. And the user UPN suffix needs to be changed to have that user get synced with Azure AD.

How to change the UPN values of users? The option is to go on premises AD and create new alternate UPN suffix as you can see in the following screen capture. How t0 Add a UPN Suffix to a Forest :-
