Does anyone know what error 8503001c means? I have activesync 4.2 installed and sync's with Exchange server. It was working fine for since I last set it up on my X51v, and now all of a sudden it stopped sync'ing with the Exchange server and gave me this error code 8503001c. I poked around and unchecked email in the option. The error went away. I then tried sync'ing email directly with the PC instead of the Exchange server. The error came back. I tried delete/add partnership, uninstall/reinstall activesync 4.2, all to no avail. Very strange.

Edit: OK the problem went away. I was having issues with the USB 2.0 controller on unrelated stuff, so I proceeded to remove all the USB controllers and rebooted the machine. Still strange though.
