Exchange 2010 ActiveSync contacts disappearing from iPhone

We are having an issue where contacts are disappearing from the owner's iphone.  Apparently this was "fixed" before but of course like every other thing that was "fixed" before me he doesn't remember what was done.

I've never had this issue before at my previous jobs (in much bigger environments) so I'm lost on this.

Problem was with third party synchronization software they have been running on the exchange server.

iCloud was affecting calendars though, so thatnks for that.

Code2 Exchange Sync was the issue.
