Drop the .msg on the EML & MSG Viewer page, or click Choose a file, and the Outlook email opens in your browser, with its pictures and attachments, on Windows, a Mac, Linux or a Chromebook. A .msg is one email saved by Outlook; the file is opened on your computer and is not sent anywhere.
Free to read messages and save attachments. No Outlook, no sign-up, no upload.
