Cannot get the built in mail app to sync properly. Contacts and Mail will sync, but the Calendar always get an error saying "Connection socket timeout".
I have tried other Mail apps, and each has it's own set of problems. The built in app seems to work the best, but the Calendar will not sync.
The phone is an HTC Inspire 4G, we are running Exchange 2003. I have already ran through the ActiveSync setup found in the forums here.
We also sync an iPhone to the server, it syncs just fine, and if we run the Microsoft's tool to test the setup it passes.
