Converting Outlook email from .msg to .eml files

EML Viewer Pro is a  versatile Windows software app. You can use it to manage, search and view emails that are formatted in a variety of common formats, including .eml, .msg, .mht, .pst and .ost files.  

One of the nice features of EML Viewer Pro is its ability to convert and export email messages from one format to another.  With version 4.7, you can now export email message content to .eml format. .EML files are formatted according to the RFC-822 spec. As an open format, it is supported by most email clients, including Windows Mail and Mozilla Thunderbird.  Because it is an open, non-proprietary format it may be desirable to convert emails into .eml files for archiving purposes.

Here’s how to convert Outlook .msg files into .eml files using EML Viewer Pro.

First, open EML Viewer Pro, and find the folder containing your Outlook .msg files.   Click on the folder, and EML Viewer Pro will read in the msg files and display them in the main list.  Select any listed email message to view it in the reading pane. Double click on an email to open it in full screen view.

Select the emails you want to convert into .eml files.  To select a message, you click on it.  To select multiple messages, hold down the control key, and click on the messages you want.  To choose all of the emails in the list, type Control-A on your Windows keywboard.  Messages that are selected are shown in the list with a blue highlight.

When you have selected the emails, you can export them in a single batch operation.  Choose “Export to EML” profile from the toolbar drop down list.
