I just performed a SBS migration on a 2003 SBS server. Everything went well except the mobile devices (4 iPhones and 2iPads) quit getting email. They still get email to their workstations, but it stops going to their devices. If we redraft the server it works for a while, then it stops for no apparent reason. Very strange and annoying. I loaded service pack 2 and all the other patches microsoft showed on Windows Update. It works fine for a while, then it just stops.
