What Is Microsoft Exchange Server Journaling?
Microsoft Exchange Server journaling lets you record a copy of, or journal, all
email communications in your organization and send them to a dedicated mailbox
on an Exchange Server. The process of journaling, therefore, is different than
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 offers various types of journaling. However, Message Archiving
supports 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.
