Converting Outlook .PST Emails to MBOX Format with Pst Viewer Pro

Are you leaving Microsoft Outlook for another email client?  Most non-Outlook clients are unable to import Outlook .pst/.ost files because the format is proprietary to Microsoft.  A workaround is to convert your Outlook .pst emails into an open email format called MBOX, or MBX.

For converting email files to different formats, PstViewer Pro by Encryptomatic LLC is a useful and affordable Windows software tool.  PstViewer Pro can read in files such as Outlook .pst, .ost, .eml, and .msg, then output the emails to different target formats, including MBOX, CSV, HTML, PDF, image files like PNG, GIF, and more.

Today’s lesson is focused on showing you how to use PstViewer Pro to convert Outlook .pst files directly to .mbox.  MBOX is an open format that is supported by most email clients (other than Outlook) including Mozilla Thunderbird.
The first step is to open PstViewer Pro and choose your .pst file.  Each email in the Pst file will be displayed on a line in the mail list.
Next, click on PstViewer Pro’s “Export” menu tab, then select “MBOX from the drop down list. The partial screen shot below shows the Export menu with MBOX selected.
