Converting Outlook Email To .EML

EML Viewer Pro is a software tool for Windows 11/10. It lets you manage directories of  EML files, which are individual email messages that may contain file attachments. If you have hundreds or thousands of EML files that you need to search and convert to different formats such as PDF, then EML Viewer Pro (also known as Pst Viewer Pro or MailDex) is a solid tool for that task.

But what if you are a Microsoft Outlook user and you want to convert your Outlook email messages into the open EML file format?   Microsoft does not natively support converting email into .eml files. Fortunately this task is easily accomplished by downloading the MessageExport add-in for Microsoft Outlook.

MessageExport will install directly to the Outlook toolbar. It is compatible with Outlook 2003, 2007, 2010 and the upcoming 2013, both 32 and 64-bit.

To use MessageExport, first select the email messages in the mail list that you want to convert into .eml files.

Next, choose “Export to EML” from the drop down list.  Finally, click the blue “Export” button to begin the eml conversion process. You may be prompted to select a folder where the .eml files can be stored.  MessageExport can convert one, hundreds or thousands of Outlook emails into .eml files.

The .eml files that are produced can be opened with EML Viewer Pro, or with any email software that supports the RFC-822 EML file format (which most do).

There are many, many other options in MessageExport. For example you can have it automatically convert email into .eml files on a scheduled basis. You setup a specific naming scheme based on information in the email. You can also export to msg, pdf, and other formats.

Convert Outlook Emails from .Msg to .Eml Files

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.
