Introduction to Microsoft Exchange Server Journaling

To determine whether you need additional journal-recipient mailboxes, consider
the number of users whose messages you want to archive and the typical load
these messages place on your mailbox servers. Depending on these factors, you
may also want to set up the journal-recipient mailboxes on a dedicated Exchange
Server—called the Exchange journaling server—that is separate from the servers
on which users’ mailbox stores reside.
Important:
•
If you set up multiple journal-recipient mailboxes for a large journaling
deployment, Message Archiving may receive multiple copies of some internal
messages from the journal-recipient mailboxes. For example, assume that
mailbox store A sends journaled messages to journal recipient A, and mailbox
store B sends journaled messages to journal recipient B. If a user in mailbox
store A sends a message to a user in mailbox store B, both journal recipients
(A and B) receive a copy of the same message. Message Archiving, then, will
receive one copy from each journal recipient and archive both copies.
•
You cannot turn on journaling for the mailbox store in which you set up the
journal-recipient mailbox. Therefore, if you are using Microsoft Exchange
Standard Edition or Microsoft Windows Small Business Server, which provide
only one mailbox store per server, you must set up the journal-recipient
mailbox on a separate Exchange Server or Small Business Server.
For more information and advice about organizing journal recipient mailboxes,
refer to the Microsoft document Journaling with Exchange Server 2003, which is
available at:
Organize Mailbox Stores
Journaling email messages can impact both the performance of your email server
and the amount of outbound corporate traffic on your Internet connection.
However, if you want to archive messages for only a specific set of users on your
network, you can organize your mailbox stores to minimize this impact, as follows:
On Exchange Server (Enterprise Edition required), ensure that the mailbox stores
for which you turn on journaling contain only those users for whom you want to
archive messages. Don’t include any other users in these mailbox stores.
When Message Archiving receives journaled messages, it compares the sender
and recipient addresses in these messages with the addresses of the users in the
organizations for which you turned on archiving on your Message Security
service. Based on this comparison, Message Archiving stores only those
journaled messages for users who also belong to the user organizations for which
you turned on archiving.
If you turn on journaling for a mailbox store that contains users that don’t belong to
one of these organizations, your server still journals their messages and sends
them to Message Archiving. However Message Archiving will not store these
messages in the archive.
