📧 open Outlook MSG on Mac
macOS has no built-in support for .msg files — they're a proprietary Microsoft Outlook format that requires Outlook for Windows or Mac to open natively. If you don't have Outlook installed, the easiest workaround is to convert the .msg file to PDF so you can read it in Preview or any browser.

About .msg to PDF conversion
Can I open a .msg file on a Mac without installing Outlook?
Not directly — macOS has no default app that reads .msg files. Your options are: convert it to PDF (which you can do free here on OpenAny), use a free viewer app like MSG Viewer for Outlook from the Mac App Store, or ask the sender to resend the email as a plain .eml file or forward it to you normally.
What gets preserved when I convert a .msg file to PDF?
The email body, sender, recipient, subject, and date are included in the PDF output. Attachments inside the .msg file are not extracted or embedded — you'll see that attachments existed but won't be able to open them from the PDF. If you need the attachments, you'll need Outlook or a dedicated .msg viewer.
Is it safe to upload a .msg file containing sensitive email content?
OpenAny deletes uploaded files and conversion results within 60 seconds of processing, and no account is required. That said, if the email contains highly confidential information — legal correspondence, credentials, financial data — you should weigh that before uploading to any online tool and consider a local desktop option like LibreOffice with the MSGViewer plugin instead.
