How to recover items that have been hard deleted in Outlook.

This article describes how to recover items that have been "hard deleted"; for example, if you do not move items to the Deleted Items folder before you delete them, these items have been hard deleted.

It is also possible to permanently delete items without first moving them to the Deleted Items folder. This procedure is called a "hard delete" as opposed to a "soft delete".

Messages are hard deleted in the following scenarios:

• You are using Microsoft Outlook, and you press SHIFT+DELETE to delete a message.
• You are working an Internet Message Access Protocol 4 (IMAP4) client or another type of client that does not first move the message to the Deleted Items folder.By default, the Recover Deleted Items functionality is only enabled on the Deleted Items folder in a user's private folders; items that are hard deleted cannot be recovered. To enable the Recover Deleted Items functionality on mail folders other than Deleted Items (for example, for Sent Items, Drafts, Outbox and Inbox folders), you must make the following changes to the registry:
1. Start Registry Editor (Regedt32.exe).
2. Locate and click the following key in the registry:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Exchange\Client\Options
3. On the Edit menu, click Add Value, and then add the following registry value:
Value name: DumpsterAlwaysOnData type: DWORDValue data: 1
4. Quit Registry Editor.
