I have the strangest problem with my X5. On my slower, older computer, it usually syncs fine - occasionally I have to do a soft reset.
On my newer computer running XP, I have problems approximately 50% of the time. I hear the sound saying that the computer knows the X5 is there but activeSync says it's "Not Connected." I've rebooted the computer, done a soft reset, still no connectivity. This occurs no matter whether I plug the USB into a hub or directly in to the back of the computer. Aaaaaccckkk!
I just moved the cradle back from the older computer yesterday. ActiveSync worked fine yesterday but not today. I really need the X5 to sync to this computer as it is my main computer.
ActiveSync version: 4.5.0
Firewall: Micro-cillin
Outlook version: 2003
