Several situations may prompt you to consider restoring your Microsoft Exchange Server 2007 database, including the following:
- A user deletes an e-mail message that was purged from their
Deleted Items folder or that was deleted with a hard delete.
Hard deletes occur when the user holds down SHIFT while pressing
- An administrator deletes the wrong mailbox.
- Messages from a former employee's deleted mailbox need to be
However, good retention practices can help you avoid the scenario of having to restore an Exchange 2007 database. With deleted item retention and deleted mailbox retention, there may be no need to restore your Exchange database to resolve the situations listed earlier. Configuring both deleted item retention and deleted mailbox retention are recommended best practices to help lessen the impact of restoring entire databases. In Exchange 2007, you can configure the following:
- Deleted Item Retention Allows you to
recover items after they have been removed from the Deleted
Items folder or hard-deleted. You must configure the Exchange
server for deleted items retention, and the item recovery must
occur during the retention period. In Exchange 2007, the
default retention period is 14 days. The actual recovery of the
deleted items is done from the client.
- Deleted Mailbox Retention Allows you to
recover mailboxes after they were deleted. You must configure the
Exchange server for deleted mailbox retention, and the mailbox
recovery must occur during the retention period. In
Exchange 2007, the default retention period is 30 days. You
can perform the actual recovery of the deleted mailbox by using
either the Exchange Management Shell or the Exchange Management
Note: For both deleted item and deleted mailbox retention, the longer the retention period, the more storage required on your server. The amount of needed storage will vary based on how many users there are and their messaging-related behavior.
