EML Viewer Pro (also known as PstViewer Pro or MailDex) 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,  .OST and .OLM 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 the latest release, 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 useful to convert emails into .EML files for purposes of email archiving, long term preservation or sharing.

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 keyboard.  Messages that are selected are shown in the list with a blue highlight.

A .eml file viewer will let you open email files created by applications like Winmail and Outlook Express. But what if you need to open other types of email files, such as Outlook .pst or .ost files or .msg files? Will you need to install three more software packages to be able to access the email stored within those files?

Now there is an email viewer available that allows able to manage multiple email formats while providing a single view across all of your different email content formats.

EML Viewer Pro by Encryptomatic LLC is an advanced email viewer. It is in use in many enterprise environments, and is available as a .msi installer package.  It is also easy enough to use that it can be used by small business and home users to manage their email.

EML Viewer Pro is also capable of reading not only .eml formatted email messages, but also Outlook .pst  and .ost files and .msg files. EML Viewer can display emails that are formatted as html, text or rich text files.  It can also convert all of these types of email formats into PDF files, including the file attachments.

All emails are not created equally. In fact, some are quite complex files. They can include html rich text, file attachments, and embedded pictures. One of the areas where email viewers often fall short is in dealing with OLE embedded objects within the email. Writing software code to handle these situations is very difficult and prone to errors, and as a result these objects are often not shown correctly, are inaccessible, and omitted during the rendering of the email.  PstViewer Pro excels at rendering these difficult emails, the product of years of experience and testing across millions of email.
