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, EmlViewer Pro by Encryptomatic LLC (also known as PstViewer Pro) is a helpful and affordable Windows software tool. EmlViewer 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 EmlViewer 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 EmlViewer 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 EmlViewer 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.

Next, select the emails you want to add to the MBOX file from EmlViewer Pro’s mail list. To select all emails, type CTRL-A. Selected emails are highlighted in blue. You can select all emails, a range of emails, or just certain emails.
To begin the export process, click the yellow “Export” button.
EmlViewer Pro will display a status window that shows the progress of your conversion.
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.
