The next time they sync, it doubles up the number of contacts on the device, killing it. The other side of this is that because it's one way, contacts entered on the device do not cross back up, and don't get backed up unless it's done manually.
Please post back if support can provide a reasonable solution to this. This is a drawback to syncing contacts from Exchange PF's, and the last time I was on with support their answer was, basically, "That's the way it has to work". Doesn't seem like a very elegant solution to a system that, for the most part, works quite well...
