Wondering what MSG files are? MSG files stand for Microsoft Outlook Item. As mentioned, the MSG files are not created on a Mac system. You can open these files only through MS Outlook on a Windows PC. The files ending in the .msg file extension are used for an Outlook Mail Message file.

From this, it is clear that Mac cannot recognize the MSG format. Let us further find out how to open these files on your device.
