I upgraded Exchange 2000 to Exchange 2003 (sp2) and migrated to new hardware over the weekend, and my clients running Outlook 2003 sp1 are experiencing issues when opening folder in the mailbox OTHER THAN the inbox or the archived .PST folders. They are able to open outlook once and see the folder no problem, but then it encounters problems and closes.(send and recieve and Inbox access works fine) I have installed sp2 and the outlook 2003 update, but the issue is not resolved. I have removed ansd reinstalled Outlook 2003-no luck. any thoughts? Thanks.
