I have a customer that has a single Exchange 2003 server on 2003 Standard OS. At one point Activesync was working for one IPHONE and then just quit. I have gone through KB 817379 and 883380 more than once. OWA and OMA work like a champ but no luck with MSASync. https://servername/microsoft-server-activesync
