Pst Viewer Pro is an email viewer for Outlook .PST, OST, MBOX, MSG, EML, and MHT files. It is much more than a viewer, however. With Pst Viewer Pro you can export email messages to different formats, convert them to PDF, reply and forward emails using your default email client, manage messages as a batch, and much more. Today’s article looks at utilizing Pst Viewer Pro’s MBOX conversion capability.
PST to MBOX
Microsoft Outlook is a wonderful tool for managing email content. Yet, for various reasons, some people find it necessary to convert their Outlook email messages to the Mozilla Thunderbird email client. In this article, we will use PST Viewer Pro to convert selected email messages in an Outlook .pst (Personal STorage file) to MBOX, an open format that can be imported to many email clients.
Use the “Download Now” button on the right side of this page to get a 15 day free trial of Pst Viewer Pro, and follow along. Note that the trial of Pst Viewer Pro will let you export up to 50 messages, which is just fine for a test. The full version does not have this restriction, allowing you to export any number of email messages.
Start Pst Viewer Pro and select your Outlook .pst file. The file may be chosen by using the navigation on the left side of your Pst Viewer Pro user interface. Click Pst Viewer Pro’s ‘+’ expander to show the folder structure of the .pst file.
Today we will export only the Inbox folder from the pst file. Click Inbox.

To begin the export of the selected emails from your PST into a new MBOX file, click the Export button (the export button is circled in the image above). Pst Viewer Pro will ask you where you where you would like store the MBOX file. Choose your desired location. In my example, I’m going to export it to my desktop. I’ll call my file “export1.”
Click Save, and the process will begin. Exporting about 3,000 messages took my lightweight laptop computer less than ten minutes.
When the process completes, my 39 MB MBOX file is stored on my desktop.
The process for importing the MBOX file will depend on the email client you are using. Please refer to your email client’s help index for specific details about importing email from MBOX files.
