MSG is a proprietary Microsoft format used by Outlook on Windows. It stores emails as a binary compound file (CFBF), which macOS has no built-in support for. Outlook for Mac uses a completely different file format internally and cannot read .msg files.
MailSnap parses the MSG format entirely in your browser using JavaScript — no data ever leaves your device.
Can I open a .msg file on Mac without Outlook?
Yes. MailSnap opens .msg files directly in your browser — no Outlook, no download, no account required.
Does Outlook for Mac open .msg files?
No. Even with Microsoft Outlook installed on your Mac, Outlook for Mac cannot open .msg files. This has been a long-standing limitation.
Is my email data safe?
Yes. MailSnap processes everything locally in your browser using JavaScript. Your file is never uploaded to any server.
Can I download attachments from a .msg file?
Yes. MailSnap extracts all attachments and lets you download each one with a single click.
What if the .msg file has formatted HTML email?
MailSnap renders the HTML body so the email looks as the sender intended, with images and formatting intact.
