We've had an annoying problem with Exchange Server 2003 on our side that I have not been able to find a fix for up to this point. I'm hoping you can help.
We have Windows Mobile phones and set them up to sync over the air with our Exchange Server. It works wonderfully ... until the end user changes their password, either as a result of expiration or choice. After that, the phone fails to synchronize, brings up a View Status screen, and the error it shows is the following:
ActiveSync encountered a problem on the server.
View Support Code (Support Code: 0x85010001)
The only way I can fix it is to delete the entire ActiveSync partnership, reboot the phone (either warm reset or battery removal and re-plugin) and then rebuild the partnership from the ground up. This is creating a lot of support calls, and is very hard to explain to the end user when they are on the road and cannot get to their e-mail.
This happens on all of our AT&T phones across the board (Blackjack 1 and 2, 8125, 8525, Tilt), so I'm sure it's either a Windows Mobile setting I need to hack in, or more likely, a setting on the Exchange Server I need to take a look at. Would anyone here know the first place to look?
