You can set up an Exchange Server so that a copy of all messages sent and received by the Exchange Server is passed directly to a journal mailbox in addition to the recipient mailbox. This is particularly useful if you want to implement a company email monitoring policy and vital if there is a possibility that you may have to produce email as legal evidence at some later date.

When setting up Enterprise Vault Exchange Journal archiving in the Administration Console, you add Exchange journal targets, policies and tasks. You also create an archive for each target Exchange journal mailbox that Enterprise Vault will archive.

An Exchange Journaling task performs the archiving. One of these tasks can service multiple journaling mailboxes. Exchange Journaling tasks run under the control of the Task Controller Service.

Exchange Server journal mailbox archiving archives all types of messages sent to the journal mailbox; it does not take account of the message classes defined in the properties of the Enterprise Vault Directory.

Items in journal mailboxes are deleted from the mailbox as they are archived, or after the vault store is backed up, and no shortcuts are created. Administrators with access permissions to the journal archives can search for messages. As journaled items may be confidential, it is important to give such access to a few trusted users only.

The Enterprise Vault Exchange Journaling task automatically detects and processes correctly any messages from Exchange Servers with envelope journaling enabled.

See the Installing and Configuring manual for more information on how Enterprise Vault supports envelope journaling.

Enterprise Vault Accelerator products can be used on journaled data; Discovery Accelerator enables legal discovery, providing features such as searching, a reviewing system and publishing; Compliance Accelerator provides message monitoring features, such as sampling, searching and a reviewing system.

As journaling generates a large amount of data, Enterprise Vault can be used to control the disk space used on the Exchange Server by continuously archiving the contents of the journal mailbox.
