Part of Exchange Server's compliancy solution is "Journaling". You can use journaling to create a copy of all messages that are sent and/or received by a particular mailbox. These copies are stored in another mailbox in your Exchange organization.
To setup journaling, follow these steps:
- create a journal mailbox. Personally I always use the name 'journal' to make it easy to identify. Make sure that this mailbox has a high quota limit to prevent journal messages to be refused;
- Open the Exchange Management Console and navigate to the Organization Configuration and select the Hub Transport option. In the results pane, select the Journal Rules tab;
- In the Actions Pane, click on "New Journal Rule". In the wizard, give the rule a name, and select the mailbox where the journal reports need to be sent to. This is the mailbox that was created in step 1. In the scope are, you can determine which messages are journaled. Also, you have to enter which user you want to be journaled.
When a message a sent to this recipient, or when this user sends out a message, a copy of the message is stored in the journal mailbox. The message is sent as an attachment in a new message to the journal mailbox. This is not really a 'big brother' scenario, but a compliancy solution. I typically see this where the management mailboxes of a company are journaled. This can be used as a single item recovery, in case messages get lost.
