Outlook MSG Considerations

Microsoft Outlook MSG files are single message files. They are different from standard RFC822 message files, and are created from the Outlook email client. Commonly, the MSG files are created by dragging and dropping a single email message to the local computer.

Requirements

  • The Microsoft Outlook email client is required. To create Outlook MSG files, Outlook must be the source email application, and it also must be the default email program for Windows. Microsoft Outlook must also be the target email application to maintain attachment names.
  • Each message is stored as a single file and has the .MSG file extension.
