We are running exchange SBS 2003 w/sp2 and have two mobile users, both on Cingular, one uses a blackjack and the other (me) at Treo 750. We have ActiveSync up and running and are able to sync OTA. But - a huge BUT - we have sporadic/intermittent times where exchange activesync stops working. Then sometime later, and that time frame varies, it starts working again. We thought it was an issue with IIS, but we got that solved and still the problem.

I know this error is a general error message, mostly associated with desktop activesync - our problem is solely with our exchange server. Does anyone have any suggestions or having the same problem and can shed some light as to why and how to fix this? Any help is greatly appreciated!!
