A .msg file is a Microsoft Outlook email message saved as a standalone file. It uses the CFBF (Compound File Binary Format) — a proprietary Microsoft format that stores the email subject, sender, recipients, body, and attachments in a single binary file.
MSG files are commonly created by dragging an email out of Outlook into a folder, or by using Outlook's "Save As" function. They're also used by legal teams, compliance systems, and email archiving software.
How do I view a MSG file without Outlook?
Drop your .msg file onto MailSnap. It reads the file in your browser and displays the full email — no Outlook needed, on any operating system.
