MSG to EML: How to Convert Outlook Email from Outlook .MSG to .EML

There are two basic formats for storing individual email messages: .eml and .msg

The .eml open message standard was pioneered by a document called RFC-822 which set the convention for creating and formatting email messages.

Microsoft, however, decided to pursue a different path.  Outlook email messages have the file extention .msg, and are not compatible with email clients like Thunderbird that open .eml files.  Microsoft Outlook can open both .msg and .eml files.

Converting Outlook .Msg emails into .Eml files ensures that the emails are accessible in an open messaging standard, which makes email more suitable for long term storing or archiving.  There are also different situations where importing email requires conversion of email from .msg to .eml.

There are various tools on the market that can accomplish this. The two tools we will look at today are developed by Encryptomatic LLC.

MessageExport for Outlook

MessageExport is an Outlook add-in.  If you already are using Outlook, MessageExport will let you save emails directly from Outlook to .eml format, as well as PDF and many other formats.

MessageExport supports Outlook 2016/2013/2010 and 2007. After installation, it becomes part of the Outlook toolbar.   Using MessageExport is as simple as selecting one or more emails from the mail list, choosing “Export to EML” from the Outlook toolbar, and clicking on the “Export” button.

PstViewer Pro Eml Viewer

PstViewer Pro (formerly called EmlViewer Pro) is an email viewer that reads .eml, .msg, .pst, .ost and other popular email file formats.

To convert .Msg to .Eml with PstViewer Pro, first select the Windows folder containing the .msg files.  Next, highlight the .msg files in the mail list that you want to convert to to .eml
Finally, select “Export to Eml” from the drop down list and click “Export.”

PstViewer Pro will then convert the msg files into eml files. Because PstViewer Pro supports many other formats, you can mix and match between them to accomplish a wide range of email conversion tasks.

EML to CSV: Bulk Convert .EML Email Files To a List

Screen shot showing CSV selected a export format.

Professionals who regularly work with E-Mail understand the importance of being able to batch convert a large number of .eml email files to a text format. Whether you need an easily searchable text version of E-Mails, or if you just need to capture basic E-Mail header information in a text format,  EmlViewer Pro can help. This capability is included with every copy of EmlViewer Pro.

How to Convert .Eml to CSV

To follow along with this tutorial, download a free trial of EmlViewer Pro. The trial will allow you to export up to 50 E-Mails per export operation.  This restriction is of course removed from the registered version of the software.

When EmlViewer Pro first starts, use the folder explorer on your left hand side to select the folder where your .eml files are stored.  EmlViewer Pro will then read those E-Mail files into an organized list.

If you want to convert all of the E-Mails in the list to .csv/text, you can select them all for export by typing Ctrol-A.  Selected E-Mails will be highlighted in blue.

Exporting .eml into .csv format lets you then import E-Mails into Microsoft Excel.

Next select the Export tab.
From the drop down list, choose the CSV export profile, as shown in the image below.

The last step is to click the “Export” button to begin the operation.  EmlViewer Pro will proceed with saving the select .eml E-Mails into a text-based Comma Separated Values (CSV) file. The .CSV file will be written to a folder location that you indicate.

Clicking on the .CSV file will cause it to open in your default spreadsheet application. In the image below, the CSV file has been opened in Microsoft Office Excel 2013.

The E-Mail content has now been organized into columns that include the following fields:
From, Subject, Date, To, CC, Message Body, file attachment information, and a link to the original .eml file.

These columns can re-arranged or deleted, searched or otherwise manipulated.

While the trial version of EmlViewer Pro restricts export operations to 50 E-Mails, there is no limited to the number of .Eml files that may be converted to .CSV in the registered version.
