We are running Exchange 2013 SP1 on Windows 2012. Our users have no problem logging into OWA with their UPN. But, if I set the users AD attribute "User must change password at next login," the next time the user logs into OWA they are redirected to the change password form of OWA and are forced to login with DOMAIN\username. They cannot use the UPN that they are used to when logging into OWA. This confuses 99% of my users. Can this be changed to allow UPN when the user is forced to change their password? TIA
