Hi, my Outlook is set up as IMAP, not POP, it keeps synched with the server, so when I read an email, it is marked as read on the server, if I delete an email it is deleted from the server as well as from the PC. For some reason the BlackBerry is not picking up these changes in the way my previous phones did. Also (may be related) the BlackBerry only ever downloaded emails that arrived after I set it up, it would not access older emails still on the server (again behaviour different to any other phone or for that matter installation of email client software such as Thunderbird or Outlook on a PC). I see others are having similar problems:
