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.
