In Exchange Server 5.5 Service Pack 1 (SP1), Microsoft added a new featurejournalingthat captures copies of user's messages within the Exchange system. Journaling lets an administrator capture all messages to another recipient (i.e., mailbox, custom recipient, or public folder) as soon as anyone submits or receives the message.
Although most private companies want to delete messages after a week or 2 for various reasons (e.g., to prevent litigants from introducing messages as evidence in criminal or civil lawsuits), some companies and government agencies require retention of every message sent through an organization. For example, the Securities and Exchange Commission (SEC) requires retention of messages that relate to a broker-dealer's business, and the State of Florida requires its agencies to store all email messages for public record retrieval under the Florida Sunshine Law.
Journaling is different from archiving. Journaling saves messages to a recipient, whereas archiving moves those messages to long-term storage where you can search for and retrieve them. Here, we describe how message journaling works and how to configure it. In a future issue, we'll review options (e.g., Microsoft Exchange Server Archiving Agent, third-party utilities) for archiving the messages you've captured in your journal. . . .
<i>Note from Greg Dodge: Messaging journaling scope can be set to the following in the registry:
1. Per Server. All messages will be journaled that go in and out of the local server, regardless of if they have previously been journaled.
2. Per site. All messages are journaled only once per site, and a stamp will be put on the mail so other MTAs in the site know the message was already journeled.
3. Per org. All messages are only journaled once in the entire org, and a stamp is put on the message so other MTAs know that the message has been journaled.
This registry setting is documented in the Microsoft article “XADM: How to Enable Message Journaling in Exchange Server 5.5 (Q239427).”</i>
