I am trying to use contact sharing in Outlook 2007 with Exchange 2007 but I have some problems. One user shares some 300+ contacts, but only about half of it is visible when accessed from another user. I didnt see that there were any limitations, or some security features enabled. Any way to solve this problem?
First you should check if some of the contacts are marked as private. If that is the case, you must unmark them private (or ask a user to do so). Also, you could try export the complete contact list and import it again. This seems funny but could also solve your problem.
