This is a pretty strange problem. I am running Outlook 2003 connected to an Exchange Server 2003 machine. When I look at the Global Address List though Outlook's Address book, it only lists about half of the people that are part of the global address list. Yet, when I access the server through OWA, I can find all of them, and they are all correct. Similarly, I can directly browse the GAL from the Exchange Server, and I can find everyone fine. Furthermore, if I just type in the person's name when creating an e-mail, it will find it, but it is the wrong e-mail address (their e-mail address has been updated). I've tried rebuilding the Offline Address Book, and Send/Receiving just the address book in Outlook, with no luck. Another possible related issue is that the missing names are all part of a group. If they are not part of a group, then they aren't missng from the GAL. Finally, I've tried using different user's computers that all have different mailboxes and everything, and I still get the exact same thing. Any help?
