.MSG Type 1
Microsoft Outlook saves email messages, contacts, appointments, or tasks in an MSG file format. That file can have more than one email field. As with usual emails, those fields contain the date, sender, recipient, subject, and the message body, or contact information, appointment details, and one or more task descriptions. Any software that uses MAPI (Messaging Applications Programming Interface) can open MSG files.
