Software

You've really broken it now haven't you ? Unless you hold down the Shift key and permanently delete them, emails don't disappear, they're there somewhere. Try putting the old PC back in place and opening Outlook. If you were running in cached mode they'll be in a local copy of the mailbox. You can then copy them to a .pst file and import them to the other PC.

Now that you have edited your post what was your original problem!!!??? :-(
