7. Change The File Extension
If the file you need to open was not directly created by Outlook, you may be able to simply change the file extension from .MSG to .EML which will enable Apple Mail to open it. Alternatively, you can try changing the file extension to TXT and open the email in TextEdit on your Mac. This also works if you right-click or CTRL-click on the file, select Open With… and select TextEdit.
8. Install Windows on your Mac
This is the most complicated and time-consuming way to open Outlook files on your Mac but may be worth it if you use a lot of Windows only applications.

This enables you to run macOS and Windows simultaneously so that you can switch between both at any time.
