What is PST / EML / MSG?

PST, EML, and MSG are common email file formats. PST is a Microsoft Outlook container that stores many messages and folders; EML and MSG store individual messages. Archiving and eDiscovery platforms ingest and export these formats to interoperate with mail systems and review tools.

Journaling

Journaling is a capture method in which a copy of every message is automatically delivered to the archive at the moment it is sent or received, independent of the user's mailbox. Journaling ensures a complete, unaltered record even if a user later deletes the original.
