All, As much as I love my iMac, I would love it even more if I could get it to sync with my work contacts. I have entered in my exchange login information into Address Book preferences (user/pass and server address) but it just doesn't seem to work. Frustratingly, it also never returns any kind of error messages either so I am just left there twirling my thumbs. Here are the details of what I am trying to get to sync: Exchange Server 2003 (my company does have OWA enabled) to my Address Book on the iMac. My iPhone syncs wonderfully and I have had no problems with it. But, Address Book can't seem to connect/or import the same contact list -- it gets nothing. I just have the feeling that it is some small detail that I am missing. Does anyone else out there have a similar setup that is working? Thanks everyone!
