Outlook Express Error : 0x800CCC17 USER CANCEL

  1. You have pressed the cancel button
  2. You may have mail that are missing headers, mail that does not conform to the mail RFC’s or a corrupt or very large file attachment on the mail server.
  3. If you pressed cancel because it is taking a long while or is timing out then the pop3uidl file may be corrupted. Close your Internet connection and all other programs. Find and delete the file, pop3uidl, reconnect and try it again.
  4. If still the same error then repeat step 3, and reboot before trying to check the mail again.
