A function of e-mail systems (such as Microsoft Exchange and Lotus Notes) that copies sent and received items into a second information store for retention or preservation. Because Journaling takes place at the information store (server) level when the items are sent or received, rather than at the mailbox (client) level, some message-related metadata, such as user foldering (what folder the item is stored in within the recipient’s mailbox) and the status of the “read” flag, is not retained in the journaled copy. The Journaling function stores items in the system’s native format, unlike e-mail archiving solutions, which use proprietary storage formats that are designed to reduce the amount of storage space required. Journaling systems also lack the sophisticated search and retrieval capabilities contained in e- mail archiving solutions..”
