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

There are two basic formats for storing email messages.  The open messagage standard was pioneered by a document called RFC-822 which set the convention for creating and formatting email messages.   Microsoft, however, decided to trod a different path.  Outlook email messages have the file exention .msg, and are not compatible with email clients like Thunderbird that open .eml files.  Microsoft Outlook however, can itself open .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.

MessageExport supports Outlook 2016/2013/2010 and 2007. After installation, it becomes part of the Outlook toolbar.   Using MessageExport is as simple as selecting one or more emails from the mail list, choosing “Export to EML” from the Outlook toolbar, and clicking on the “Export” button.
