How to open an MSG file

Drag your .msg file into the box above, or click "Choose a file" — this msg file viewer works online and lets you view a .msg file without Outlook installed.
The headers, body and attachment list appear below.
If the body only shows plain text, that message stored its formatting as RTF — see the known limitation below.

Tested with

.msg files saved from Microsoft Outlook (desktop), covering plain-text and HTML bodies and regular attachments.

Check it yourself

The email body renders in a sandboxed frame with scripts disabled, so nothing in the message can run code. Open your browser's developer tools and watch the Network tab while you open a file — nothing is uploaded. See the full privacy page for details.

Known limitations

Some Outlook messages store their formatted body as compressed Rich Text (RTF) rather than HTML. Only the plain-text body can be shown from those right now — a note appears above the body when it happens.
Very large attachments can be slow to render, since everything happens on your device.
Embedded (nested) .msg attachments aren't opened automatically yet.

FAQ

Why does the body only show plain text?
That message's body was stored as Rich Text (RTF) rather than HTML — a common Outlook quirk. Seewhat winmail.dat is for the related fix.

Can I save what I see as a PDF?
Yes — use MSG to PDF for a downloadable, selectable-text PDF.

Can I open a .msg file without Outlook?
Yes. This .msg opener reads the file's format directly in your browser, so you can view a msg file without Outlook, an account or an upload.
