Allow blank email, then send email back to UKG

Can we have the email from UKG blank and then allow the updated email in AD, to be sent back to UKG?

Yes, this is possible.

  1. Set the Mail mapping to use the expression: User.userPrincipalName

This means that when an account is provisioned in AD, the users mail address will be set to the same value as the assigned UPN.

  1. Enable the Active Directory is the source of truth setting for the Mail mapping

This means that after the mail is set to the UPN in AD, the mail address will be sent back to the UKG employee record to show the correct mail address that was assigned in AD.
