Two that I have used are Byari's InsightServer and 
Stalker Software's CommuniGate Pro.  So far I prefer
CommuniGate Pro.  It is highly flexible.  Although it
is completely closed, they have created a perl 
interface library that allows you to do just about
anything you want.

Both have a Outlook connector, but CGP's connector
works more like Exchange.  Bynari's connector replicates
information from the server to the client.
