You must create a dedicated Mailbox Store for envelope journaling to properly establish the journaling process. Mailbox Stores process all messages from existing mail servers. Microsoft recommends placing the Exchange Mailbox Store (that contains the journaling mailbox) on drives other than those which hold user mailboxes.
To add a new Mailbox Store on your Exchange Server, follow these steps.
