Event Import can import emails from Exchange servers that have envelope journaling enabled.
The envelope journaling feature in Exchange enables organizations to archive transport envelope data. This includes the actual recipient information that the transport system used to route and to deliver the email. In particular, it identifies the recipients who actually received the message, including recipients from distribution lists and blind carbon-copy (Bcc) recipients.
Unlike message-only journaling, which copies emails to be archived into a designated mailbox, envelope journaling copies into the designated mailbox an envelope message (a ‘wrapper’ email) that contains a journal report plus an attachment containing the original email. The journal report (the body text of the envelope message) contains the transport envelope data of the original email.
However, when an email is imported from a mailbox on an Exchange server that has envelope journaling enabled, CA DataMinder extracts the journal report and the attachment containing the original email and discards the envelope message. This process is referred to as ‘de-enveloping’. CA DataMinder then creates a new event based on the original email and the actual recipient details. When a reviewer searches for this imported email in the iConsole or Data Management console, the console displays the original email.
Starting with Microsoft Exchange Server 2010, Information Rights Management (IRM) allows Microsoft Outlook and Microsoft Office Outlook Web App users to protect their messages. In the context of envelope journaling, "journal report decryption" allows Exchange administrators to save a clear-text copy of IRM-protected messages in the journal emails, along with the original, IRM-protected message.
When CA DataMinder encounters such journal emails, it extracts the clear-text copy of the IRM-protected messages.
If journal report decryption was disabled at the time an IRM-protected message was journaled, then the journal email only contains the original, IRM-protected message, and CA DataMinder can only extract the IRM-protected message.
Note: Recipients extracted from the journal report are searchable in the iConsole or Data Management console. That is, reviewers can specify a recipient when searching for emails imported from an Exchange server that has envelope journaling enabled.
