The clients that I support run WIndows XP with Outlook 2002. I have several users that get the message "Requesting data from exchange server" several times an hour and it interferes with their production. The only time I have seen this error on my PC was when there were known network problems. I have a customer that is having this problem now but there are no known network problems right now and the server is fine. Anyone know of other fixes for this chronic problem? Could it be a firewall issue?
