I'm having a problem in Outlook XP (2002) that seems to have recently "appeared". Apparently when users are composing emails and click the "To:" button to select email recepients, contacts that are in their personal contacts folder are not listed. I did double check to make sure that their contacts folder is set to display as an address book, and I have attempted removing and recreating their Outlook address book from from Tools->Options->Email Accounts screen.
The odd part of this behavior is that if I do a search from within an email for a contact that is listed within their Contacts folder, it finds it without any problem. I've tried restarting the Exchange server w/o result. Any help would be greatly appreciated.
