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.
- Start Registry Editor.
- Locate and then click the following subkey:HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Exchange\Client\Options
- 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.
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.
More informationWhen 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.
