How to open a .msg file without Outlook

A .msg file is Outlook's own way of saving a single email — and if Outlook is the only thing that reads it, a stray attachment can feel impossible to open. It is not. MSGView reads .msg files right in your web browser, with no Outlook, no Microsoft 365, and no install. It works the same on Windows, Mac, Linux, ChromeOS, and your phone, and the file never leaves your device.

Open a .msg without Outlook in 3 steps

1. Open MSGViewGo to msgview.app in any modern browser. There is nothing to download and no account to create.
2. Drop your .msg fileDrag the file onto the page, or tap to browse for it on a phone. It is parsed inside your browser tab — never uploaded — up to 100 MB.
3. Read the emailSee the sender, recipients (including Bcc), date, body, and attachments instantly. Convert it to PDF or EML if you want to save or forward it.

Works on Windows, Mac, and your phone

Because MSGView runs entirely in the browser, the platform does not matter. On Windows, it is a fast alternative when Outlook is missing or the New Outlook refuses the file. On a Mac, where Outlook often is not installed at all, you can finally read that .msg without buying software. On a phone or tablet — iOS or Android — open the attachment straight from your mail app and tap it into MSGView. Same page, same result, no per-device install.

MSGView also handles the messy edge cases that trip other tools up: it decodes winmail.dat (TNEF) attachments, opens nested or embedded emails, reads .eml files too, and renders CJK, Cyrillic, and other encodings correctly instead of showing garbled text.

Private by design

Opening an email you did not send should not mean handing it to a stranger's server. MSGView parses everything locally in your browser tab, so your .msg file and its contents never touch the internet. Nothing is uploaded, nothing is stored, and there is no sign-up, no watermark, and no cost. If you want proof, open your browser's Network panel while you load a file — you will see no request carrying your email out.
