This feature helps to quickly recover accidentally deleted files or randomly deleted. After being deleted from Deleted Items, elements can still be restored if the Exchange Server 5.5 installation server is configured to retain the deleted items. To determine if the server has been configured for this functionality, you can open the Properties dialog box containing information about the common and private objects stored under the Server label.

You can also permanently delete elements directly, no need to put them in a temporary storage area in the Deleted Items folder. This procedure is called "hard delete", as opposed to "soft delete".
