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.

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.

EmlViewer Pro (also known as PstViewer Pro) is a Windows email viewer. You can use it to discover and export .eml emails to to PDF and many other formats.

EmlViewer Pro lets you make your own email export profiles. What is an export profile? Its a pre-set instruction that tells EmlViewer Pro exactly what to do with the emails you have chosen.

EmlViewer Pro comes with many pre-built export profiles. You’ll find them in the export tab drop down list.

You can edit any of these export profiles and add more features, such as naming files, copying files, setting page size, export format and much more.

To make changes to an export profile, just select it and click the “Edit Profile” button.

Editing existing profiles is good, but if you’re ready to take it to the next level, you can design completely new email export profiles by clicking the “New Profile” button.

This starts the “New Export Profile” wizard. Just follow along and make the choices that will best fit your project.

EmlViewer Pro gives you many options. If you’re satisfied with the “out of the box” email export options (and many people are), then there’s no need to make profile changes. However, if you think that EmlViewer Pro would be a little bit better if an export profile could do a few more things, then investigating the profile settings could be exactly what you need to get the job done perfectly.
