I often have the need to sync Outlook between a desktop and a laptop and have tried many different PSTSync and SyncPST type programs and have not found one that works 100%. For example: One did fairly well except it did not sync groups in the address book, another did not bring over sub folders, another did not bring over the icon or info that shows that I had already responded to an email and many did not work if Outlook was open on either machine. I even had the problem of one of the computers would download duplicate emails from the server for mail that I had already sync'd. I am looking to sync Outlook from a Desktop to a laptop over the network and have then 100% exactly the same? Any suggestions other than going to Exchange.
