I would like to synchronize the contacts lists of two users on our Exchange 2007 server. They connect to the Exchange server using Outlook 2007. I would like this solution to be server-based so the users don't need to run a separate piece of software on their computers. I did find a program named "CodeTwo" which looks like it will do the job, but the price seems pretty steep for such a seeming simple task. Is there an alternative program that is cheaper or, better yet, free? Will Exchange do this without third party software?
