If you delete an email in an email program, it is usually moved to a Deleted Items folder (as in Outlook Express) or similar. The Deleted Items folder is like a Recycle Bin for emails, and gives you a chance of restoring messages deleted in haste or in error. However, Outlook Express has an option to clear the contents of the Deleted Items folder whenever you close the program. If you enabled that setting, you'll be out of luck recovering email from Deleted Items unless you do it straight away.
If an email is moved from one folder to another, or to Deleted Items, the message is copied to the destination folder and then deleted from the first. As with files on a hard drive, when a message is deleted from a folder it is not physically erased. The deleted email does not get overwritten until the mail program tidies up or compacts its database and it is possible to recover deleted emails intact.
