Hi all, I have a single mailbox which is giving me problems. The client runs Office XP. Whenever the user tries to move a mail, read an e-mail or (sometimes) change folders, she gets the 'Requesting data from Exchange Server' box, and takes around 10 seconds to open or move the mail. All other mailboxes (even on the same client) work perfectly. What's the cause of this? Any idea? Thanks and regards. Andy.
