You have "hard deleted" (permanently deleted) items in Microsoft Outlook, and you want to recover the items. For example, if you do not move items to the Deleted Items folder before you delete them, these items are hard deleted. Therefore, you cannot recover them from the Deleted Items folder.
Note If your server that is running Microsoft Exchange Server is not configured to keep deleted items, the Fix this problem button or the steps to change the registry do not work. This solution requires that you use an account that uses Microsoft Exchange Server 2000 or later versions. Most home and personal accounts do not use Exchange.
This section, method, or task contains steps that tell you how to modify the registry. However, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For added protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs. For more information about how to back up and restore the registry, click the following article number to view the article in the Microsoft Knowledge Base:
How to back up and restore the registry in Windows
By default, the Recover Deleted Items functionality is enabled only 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 the Deleted Items folder (such as Sent Items, Drafts, Outbox, or Inbox), change the registry by following these steps:
- Start Registry Editor.
- Locate and then click the following subkey:
- On the Edit menu, click Add Value, and then add the following registry value:
Value name: DumpsterAlwaysOn
Data type: DWORD
Value data: 1
- Close Registry Editor.
You can use an administrator's computer or a user's computer to make this change to the registry. After you change the registry, start Outlook, and then click Deleted Item Recovery
on the Tools
menu. A list of items that were hard deleted during the retention time that is set on the server is displayed.
If you are an administrator, you can set this functionality for all user workstations. To do this, use your computer to change the registry for all user workstations, and then open the affected user's mailbox as an additional mailbox. You can then recover deleted items from the user's mailbox mail folders. Note
If you are an administrator, and you want to open another user's mailbox to recover items in the user's private folders, your Windows NT account must have user permissions for that user's mailbox object. You must also add that user's mailbox to your own profile. To do this, follow these steps:
- Open Control Panel, and then double-click Mail.
- Open the Services properties, and then double-click Microsoft Exchange Server.
- Click the Advanced tab, and then click Add to add the mailbox to your profile.
When you delete items from a folder in a mailbox, the items first are shifted to the Deleted Items folder in the mailbox. You can then delete these items from the Deleted Items folder. This functionality protects you from accidentally deleting an item. After you delete the items from the Deleted Items folder, these items can still be recovered if the Exchange Server computer is configured to keep deleted items. To determine whether the server is configured in this manner, open the properties of the public and private information store objects under the Server object.

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 using 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.

The Recover Deleted Items functionality in Outlook 98, in Outlook 2000, Outlook 2002, and in Outlook 2003
In Microsoft Outlook 98, the Recover Deleted Items functionality is available only for mail folders (for example, Deleted Items, Drafts, Inbox, Outbox and Sent Items folders). Therefore, items that are hard-deleted from non-mail folders (for example, Contacts and Notes folders) cannot be recovered. However, in Outlook 2000, Outlook 2002, and Outlook 2003, the Recover Deleted Items functionality is available for all folders; if you make the registry change described earlier in this article, you can recover hard-deleted items from non-mail folders.
