MSG to EML: How to Convert Outlook Email from Outlook .MSG to .EML

There are two basic formats for storing individual email messages: .eml and .msg

The .eml open message standard was pioneered by a document called RFC-822 which set the convention for creating and formatting email messages.

Microsoft, however, decided to pursue a different path.  Outlook email messages have the file extention .msg, and are not compatible with email clients like Thunderbird that open .eml files.  Microsoft Outlook can open both .msg and .eml files.

Converting Outlook .Msg emails into .Eml files ensures that the emails are accessible in an open messaging standard, which makes email more suitable for long term storing or archiving.  There are also different situations where importing email requires conversion of email from .msg to .eml.

There are various tools on the market that can accomplish this. The two tools we will look at today are developed by Encryptomatic LLC.

MessageExport for Outlook

MessageExport is an Outlook add-in.  If you already are using Outlook, MessageExport will let you save emails directly from Outlook to .eml format, as well as PDF and many other formats.
