Per-User Journaling
Journaling a message is the process of keeping a message from one or more senders based on
long-term storage, legal, regulatory, or human resources requirements. Exchange 2000/2003
essentially had one option for message journaling: create an additional mailbox store and move
any mailboxes that must be kept to that mailbox store. Note that a true journaling solution hap-
pens before the user has any input into the process; a message is intercepted prior to or at the
time of delivery via transport rules or by rules set on the mailbox database. A true message
journaling feature produces a message envelope header that exposes the sender and recipient
information as well as containing the original message. Exchange 2010 has many new options
with respect to retaining messages; however, only the first two are considered true message
journaling features:
◆ Messages can still be retained based on the journal settings on the mailbox database.
◆ Messages can be retained using a new hub transport feature called a journaling rule that
allows messages to be retained based on a single sender or distribution group membership.
◆ Messages can be retained based on folder or content type using managed content settings;
note that this is not considered true journaling because it is merely moving mail from one
folder to another after the fact.
◆ Messages can be retained using transport rules by examining sender, recipient, message
priority, message classification, or message content. This solution does not create a true
journaling message.
