How to Convert Emails From Outlook .MSG to .EML

This article will show you how to convert Outlook .msg files to .eml files.

Msg email files are created by Microsoft Office Outlook.  An Msg file contains a single email message and any file attachments.  When an Outlook email message is copied outside of Outlook’s .pst or .ost database file, it is saved as a .msg file. Usually, the file name will be the email subject, such as “monthly report.msg”

If you have Microsoft Outlook for Windows, you can open an .msg file by clicking on it.  Because .msg files are a format that is proprietary to Microsoft, you may want to bulk convert Outlook .msg files to .eml files.  .Eml files are an open format supported by other email clients.

EmlViewer Pro is a handy tool for managing and converting email content.  It can read both .msg and .eml files, as well as Outlook .pst, .ost and .mbox files.   

While Outlook can open individual .msg files when you click on them, it does not search or organize .msg or .eml files.  EmlViewer Pro is useful for reading in a folder with hundreds or thousands of .msg or .eml files, searching them, and also exporting them to different formats.

Use EmlViewer Pro’s search feature to identify the .msg files you want to convert to .eml.

To select an email, highlight it in the list by clicking on it.  You can hold the control key and select multiple .msg emails for conversion.  To select all emails in the list, type control-A.

Now that the .msg files have been selected, click on the “Export” tab. From the dropdown list, select “Eml” export profile and then click on the “Export” button.

EmlViewer Pro will now begin converting the selected files from Msg to Eml format.

When the process is complete, you can use EmlViewer Pro to select the folder where your new .eml files reside, and they will be read into the mail list.

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.
