📧 Outlook MSG file won't open on Chromebook
Chromebooks run ChromeOS, which cannot install desktop applications like Microsoft Outlook, so .msg files — Outlook's proprietary email format — have no native app to open them. The simplest fix is to convert the .msg file to PDF, which every Chromebook can open instantly in the browser.

About .msg to PDF conversion
Can I open a .msg file directly on a Chromebook without converting it?
Not easily. ChromeOS has no built-in .msg support, and Microsoft Outlook is not available for ChromeOS. There is a Chrome extension called 'MSG Viewer for Outlook' that can display .msg files in the browser, but it may not render all formatting or attachments correctly. Converting to PDF is more reliable for reading the full email content.
What does OpenAny actually convert from a .msg file?
OpenAny extracts the email body, sender, recipient, subject, and date from the .msg file and renders them into a readable PDF. Inline images embedded in the email body are generally preserved. However, file attachments inside the .msg (such as a Word document attached to the email) are not extracted — only the email itself becomes the PDF.
My .msg file came as an email attachment — how do I get it onto my Chromebook to convert it?
Download the .msg file from your email to your Chromebook's Downloads folder as you would any attachment. Then go to OpenAny.io, upload the file, choose PDF as the output, and download the result. The whole process takes under a minute and no account is needed. Your file is deleted from the server within 60 seconds of conversion.
Is there a way to open .msg files on Chromebook without any conversion tool?
If your Chromebook supports Android apps (most do), you can try installing 'Email MSG Viewer' from the Google Play Store, which can open .msg files directly. Alternatively, if your school or workplace uses Google Workspace, ask the sender to forward the email normally rather than sharing the .msg file, which sidesteps the problem entirely.
