Note: This feature only works for Outlook email that is on a  Microsoft Exchange Mailbox and your Microsoft Exchange Provider sets a time limit on how long the exchange server holds onto the permanently deleted email.

A typical setting is for the Exchange Server to hold onto deleted mail for 48 hours, and then emails are purged from the exchange server. Emails needed after that time would need to be recovered from your Exchange server backups.

Launch Outlook 2010 and logon.

Choose “Folder” from the top menu

Highlight the “Delete Items” folder

Click the “Recover Deleted Items” button at the top

Your deleted items will be listed, highlight the email(s) you want to recover and click the “Recover Seleted Items” button.

These emails will be restored to your “Deleted Items” folder.
