Why convert MSG to EML?
.msg files only open natively in Microsoft Outlook. .eml opens in almost every mail client on every OS - Apple Mail, Thunderbird, Gmail, and most others read it without any plugin. Converting to EML is the portable alternative when archiving a message or sharing it with someone who does not have Outlook.
