Convert .Pst to .Eml

Converting E-Mail in Outlook .Pst files to .Eml files

Outlook .pst files are e-mail database files written in Microsoft’s propriatary format. One .pst file can contain many e-mails. .Eml files are individual e-mails formatted in an open specification (RFC-822). Because .eml files are an open format, they are ideal for e-mail archiving and long term storage.

Converting Outlook .pst to .eml can be accomplished with our EmlViewer Pro software.  EmlViewer Pro can read multiple e-mail formats, including .eml, .pst, .ost, and .msg.  It also include the capability to convert e-mail in many different ways. Today we will show step-by-step how to convert from an Outlook .pst to .eml files. We invite you to download a free trial of EmlViewer Pro and follow along.

When EmlViewer Pro (also known as PstViewer Pro software) loads, first select the .pst file containing the e-mail messages that you want to convert to .eml. Use the explorer navigation to locate the .pst file. You can expand the .pst file and see it’s folder structure.  To export all e-mail in the .pst file, select the the top folder.  You can also choose to select a specific folder and then export the email it contains to .eml format (or any of the other supported formats).

 When a .pst file is selected, the messages will be read into a list. Click on the list and type “Control-A” to select all of the e-mails in the list.

Next, from the Export Tab, choose “EML” as the desired conversion format.

EmlViewer Pro will now begin exporting the e-mail messages you selected in your .pst file into .eml files. The resulting .eml files will be saved to a Windows folder that you specify.

This process works on individual selected e-mail messages, or you can select hundreds or even thousands of files.

Converting Outlook Email To .EML

EML Viewer Pro is a Windows software tool for managing directories of Outlook EML files. If you have hundreds or thousands of EML files that you need to search and convert, then EML Viewer Pro 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.
