Outlook 2010: Recover Deleted Emails

Even though Outlook 2010 does not support recovery of deleted emails directly, you can recover your emails even after hard-core deletion without using any third-party components. Through successful integration of Outlook 2010 with Microsoft Exchange Server you can make it possible to recover the deleted mails. This function would only be available for POP3 mail account, you can’t revert any mails from IMAP account; Gmail, Yahoo, AOL, etc.

Launch Outlook 2010 and from left sidebar, under Outlook Data File, click Deleted Items. Now navigate to Folder tab. In Clean Up group you will see Recover Deleted Items button is grayed-out.

To enable this option you need to properly configure Exchange server 2007/10 on your system. After proper configuration if it is still grayed-out, then first you need to close Outlook 2010 if it is running. From taskbar click Windows Start Orb button, type regedit and hit Enter.

Note: Enabling this feature requires modifying the registry, before you start off with it, make sure that you understand how to restore the registry and backup the concerned registry files to prevent occurring of any erratic response.

If Exchange Server is properly configured, then it should work for you.

After complete verification if it is still grayed out, contact your system administrator.

    •  Do you guys use Exchange for Emails? This only works if you use Microsoft Exchange as your email server.

      In Outlook 2010: Go to File > Account Settings > Account Settings > Email tab

      Do you see an entry with a “type” of Microsoft Exchange? If you don’t, this won’t work for you.

  8. Now why would I want to do this, when I can simply go into Deleted Items folder and do restore/move to folder thingy/ Or I could also access the OWA and download the items once again.

    Am I missing something, please correct?

    • you are missing a whole bunch. This is for exchange, and once you empty for deleted items folder, it looks to be gone. I am gathering that you have never emptied it. Exchange keeps 3 months worth of deleted emails outside of the client (do you know what that is?). This function described allows a user to view and restore a deleted item. It still has time limitations though.
