Message journaling lets you capture messages sent or received within an Exchange store to an additional location for historical retention or other purposes. Users must have the "Archive all messages sent or received by mailboxes on this store" enabled. There are a number of options for the journaling process:
- Standard. In this mode, Exchange captures and duplicates regular messages (sent or received) to the journaling recipient, but it doesn't send Messaging API (MAPI) reports such as read receipts or out-of-office notifications.
- BCC Journaling. This mode is the same as standard journaling, but it also captures BCC recipients on messages and sends them to the journaling mailbox.
- Envelope Journaling. This mode provides all the functionality of BCC Journaling, plus it captures Request for Comments (RFC) 2821 and 2822 recipients, distribution group expansion, and MAPI reports such as nondelivery reports (NDRs), read recipients, and out-of-office notifications.
When selecting the object to receive the journaling message, you should select a regular Exchange mailbox rather than a public folder because public folders don't support certain types of reports.
