MSG and EML are both file formats for emails, but they are not the same. MSG is the format used by Microsoft for Outlook messages, while EML is the format used by most other email programs. Although MSG is a better format for storing messages than EML, EML files are a convenient format for transferring messages between different email clients and systems.
  • Outlook uses the MSG format to save messages, contacts, calendars, tasks, and other items as individual files on the disk.
  • Only email messages can be stored in EML files.
  • MSG files contain all the fields and internal properties of messages and other Outlook items.
  • EML files contain most of the message data, including attachments, but some Outlook internal properties and fields cannot be stored in EML format.
  • MSG is the Microsoft Outlook internal format. To work with such files, you need MSG Viewer or Outlook to be installed on your computer.
  • Most often, MSG files take up more space than EML.
