How to Recover Deleted Folders From Outlook
Microsoft Outlook is a program that allows users to send and receive emails, manage their calendar and create an address book. It should come as no surprise then, that Microsoft Outlook users send and receive many personal documents through this program. However, if you've deleted a document that you realized only too late, shouldn't have been deleted, there is a way to recover it. Please use the following method with caution, as misusing it could result in having to reinstall your entire operating system.
Exit Microsoft Outlook.
Click Start>Run and type "regedit" into the empty bar. Click "OK" when finished.
Open the following folders by clickinig the "+" button located on the left hand side of them: My Computer>HKEY_LOCAL_MACHINE>Software>Microsoft>Exchange>Client. Click the "Options" folder underneath "Client" to open it.
Click Edit>New in the toolbar to open another menu. Click "DWORD Value" from the list of given options.
Type "DumpsterAlwaysOn" as the name. Make sure not to put any spaces in between the words when typing it. Right-click the folder and set the DWORD Value to 1.
Restart Microsoft Outlook and your deleted folders should be recovered.
