If you don’t have access to or don’t want to use third-party applications, there is another way to view the contents of an MSG file on Mac.
It contains all the information related to an email such as the sender’s name, subject line, recipient’s address, the body of the message, and any attachments. MSG stands for Message Store, which is a proprietary file format used by Microsoft Outlook to store emails. Once you have the application of your choice installed, simply open it up and select the file you want to view. There are many such programs available for Mac users that allow viewing any type of files on Mac. The first option is to download and install a third-party application like an MSG to PST converter that can view the contents of an MSG file. Fortunately, there are several ways to view such a file on your Mac computer.
If you’re on a Mac, you won’t be able to open MSG files natively. It’s likely that when you receive shareable data from someone using Microsoft Outlook for Windows, it’ll come in the form of an MSG file.
