The Outlook Connector is more than just a "plug-in" for Outlook. It is a full message store provider for Outlook. The Outlook Connector makes it possible for Outlook to connect to groupware IMAP servers just like it does, natively with Microsoft Exchange. Other plug-ins for Outlook simply synchronize data back and forth. The Outlook Connector gives the end-user a full groupware experience between Outlook and the IMAP groupware server.
