I have an office that it using Outlook XP, with all the updates installed, and connecting to an Exchange 2000 server for email. All accounts are operating correctly except for one, that's having a very strange problem. They are on the exchange mainly for the calendar and contacts sharing, via the "file, open, other user folders" method. There is one user that when any of the assistants open his contacts, they are all not displayed correctly. At the bottom of the opened contact window it shows 1200 contacts....but only about 100 of them are viewable. If you check his contacts folder that is shared on his machine, all 1200 of them are viewable. I have removed and re-enabled the shares with office users, but still not getting the correct list of contacts. When you access his contacts from his machine, all are correctly viewable. Also ,of course, when viewing other users folders from his machine, the contacts are also correctly viewable. Any ideas???
