We just upgraded our network to a citrix server, and with the server upgrade, moved from WP8 to WP10. Now no one can create an address book. Our techs have been on the phone with Corel for hours, whose only suggestion has been to remove WP10, and reinstall. This is has been done 3 to 4 times, but with no results other than really annoying all users on the system. I am desperate. Does anyone have a cure?
