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.

Appending .EML Emails To An Existing .PDF File

Encryptomatic LLC, the developers of email viewing software, has released update 4.7 for both EML Viewer Pro and EML Viewer Lite.  These releases include PDF Append, a new pdf management feature for people who regularly need to save .eml files or other email file types to a single pdf file.

The PDF Append capability helps you convert an individual .eml file into a new or existing pdf file. This is a useful feature if you want to create a single pdf file that contains multiple email messages. One of the use-cases for PDF Append involved a legal assistant who was given the responsibility to collect specific email communications into a single pdf file.  Prior to this ability being added to EML Viewer Pro, she would export the messages individually and then use different software to merge the pdf documents into a single file, a process she found cumbersome and time consuming.

With PDF Append, she can now export these email messages to a new or existing pdf file. As the emails are discovered, she can append them to a single pdf document, with no need to run another software package.

To use this functionality, first start EML Viewer Pro or Lite and then select the folder containing your .eml files.  The software can also read .msg, .mht, .ost and Outlook .pst files.  Click on an email you want to export so it is highlighted in the mail list.  Now, click the +PDF button and enter a name for the file. The email message will be converted to PDF.

To add another email to the PDF file you just created, follow the same process, except select the pdf file you just created as the target.  The previous PDF file will be appended with your new email message.

EML Viewer Pro and Lite are very flexible email views. In addition to .eml files that are created by Outlook Express, Windows Mail and other email clients, they can also view and search Outlook .pst, .ost, and .msg files, and also .mht files. The PDF Append function works with all of the email formats supported by EML Viewer Pro and Lite.
