You can import MSG files into Outlook using a corresponding command found in the main menu. The tool supports both types and allows the user to choose between the two. MSG files can be binary (if generated by MS Outlook) or text-based (if saved in The Bat!, Zimbra or PMMail 2000). The MSG file format is the native Outlook data format for storing messages with attachments, contacts, tasks, and other types of objects. The program is a compact tool that can export MSG files from user-defined source folders and transfer them to a specified MS Outlook profile or a PST file. Conversion and import can be easily automated, and this is what MSG to Outlook Transfer was designed for.
