What Is Microsoft Exchange Server Journaling?
Microsoft Exchange Server journaling lets you record a copy of, or journal, email
communications in your organization and send them to a dedicated mailbox on an
Exchange Server. The process of journaling is different from archiving. Journaling
is simply a means of recording your users’ messages. Archiving, on the other
hand, is a means of storing those copies in a separate environment for the
purposes of regulatory compliance, data retention, or server maintenance.
Once you enable journaling on Exchange Server, you can then configure your
server to forward journaled messages to Message Archiving.
Exchange Server 2007 and 2010 and Message Archiving both support only
envelope journaling. This type of journaling copies the body of an email message
and its transport envelope information (P2 header). The envelope information
includes the sender and all recipients, including BCC recipients and recipients in
distribution lists, which is required data for compliance with most regulations.
Which Messages Do Microsoft Exchange Server 2007 and 2010 Journal?
Microsoft Exchange Server 2007 and 2010 offer two types of journaling:
• Standard journaling, in which all messages sent from or sent to addresses
on a specific mailbox database are journaled
• Premium journaling, which offers the following options:
• Internal scope: Messages sent and received within the Exchange
organization are journaled.
• External scope: Messages sent from or sent to addresses outside the
Exchange organization are journaled.
• Global scope: All messages that pass through a Hub Transport server
are journaled.
• Journal Recipients: Only messages sent to specific SMTP addresses
(mailboxes, contacts, distribution lists) within a scope are journaled. If no
recipients are specified, the scope takes precedence.
