I had 10 users working fine for months then after a reboot Monday devices were not getting e-mail. I have deleted and re-added just about everything. Although a few times it started working we would eventually have it crap out again. I am here to find some help.

I have ZCS 5.0.15, Blackberry Manager, Windows Server 2003 Service Pack 2, ZCB 5.0.18, Office 2007 SP2.

What log entries would someone here need to assist me in figuring this problem out?
