What is a .msg file?

A .msg file is Microsoft Outlook's proprietary format for saving email messages. When you save or export an email from Outlook, it creates a .msg file stored in the Compound Document File format (OLE2). Unlike the standard EML format, .msg files are binary and can only be opened natively by Microsoft Outlook.

If you've received a .msg file and don't have Outlook — or you're on macOS, Linux, or a mobile device — this tool opens it directly in your browser. No software to install, and your files are never uploaded anywhere.

If you have an EML file instead, use our EML viewer and converter. For winmail.dat files, use the winmail.dat extractor.
