The email application Microsoft Outlook is installed in every installation of Microsoft Office. For Windows users, its a stripped-down version called Microsoft Outlook Express. Both of these applications save any deleted emails so you can retrieve them if needed. This is beneficial for people who accidentally delete email or realize a deleted email is still needed several days later.
Click the Windows Start button and select "All Programs." In the list of icons. Select "Microsoft Outlook." You may also have a Microsoft Outlook icon on the desktop or on your tool bar next to the start button.
Click the "Sent" items directory on the left window pane. The "Sent" directory holds all the emails you've sent until you delete them. Verify that you deleted the item.
Click the directory icon labeled "Deleted Items." This directory holds all the emails you've deleted whether intentionally or accidentally. The list is grouped by date, but you can click the "Subject" bar or the "From" bar to sort them by subject or by sender.
Right-click the email you want to restore. Select "Move to Folder." A dialog box appears with a list of folders included in your Outlook email client.
Select the folder to move the email message and restore it. Once selected, click the "Ok" button. The email message is restored and removed from the deleted list.
Deleting items from the "Deleted Items" directory in Microsoft Outlook permanently deletes the email.
