How to Enable Standard Journaling
It is recommended that you designate a dedicated Exchange server as the journaling server. Additionally, if you use a dedicated journaling server, you do not have to enable standard journaling on the server. Enable journaling only on those servers with mailbox stores for which you want to journal.
Before You Begin
Review your overall journaling strategy to verify that journaling is enabled on appropriate Exchange server.
To enable standard journaling
In Exchange System Manager, expand Servers, expand <your Exchange server>, expand <storage group>, and then right-click the mailbox store.
On the General tab, select Archive all messages sent or received by mailboxes on this store, and then click Browse to specify a mailbox as the journaling mailbox. All journalized messages for senders on this mailbox store are sent to the mailbox you specify.
