Are you looking for the best way to convert DBX to PST? So, you are absolutely at the right place. In this article, we will describe the simplest & easiest method for converting Outlook Express DBX file to PST file format. During the process, we will show you how to keep your emails, attachments, and other important information without any issues.

Outlook Express or Microsoft Internet Mail and News utility is a desktop-based email client application. It was developed by Microsoft to send or receive emails, news, information, etc.

Now, this application has been discontinued by Microsoft after launching the Outlook series. Outlook Express saves the mailbox data in DBX format which is an outdated file format.

On the other hand, Microsoft Outlook has become the go-to-choice for email communication requirements with its modern versions like New Outlook, Outlook 2021, 2019 and Office 365 that offer advanced security and features. In addition, Microsoft Outlook provides a better interface, speed, accuracy and many features to manage emails, contacts, calendars, attachments, tasks and journals easily.

Because Outlook Express is an old and outdated email client application, that’s why we get a large number of conversion requests daily from various locations to convert DBX to PST.

Can You Convert DBX to PST Manually for Free? Reality Check

When users often look for DBX to PST conversion, they usually search for a free manual method. Historically, IT administrators use a bridge method via Windows Live Mail to move Outlook Express data to Outlook.

For your information, this is how manual method was supposed to work:

  1. First, import DBX files into Windows Live Mail.
  2. Then, use its export feature to migrate the emails to Microsoft Exchange (MS Outlook).

Expert Warning- Why should you avoid this method today when you find it in dozens of tutorials online. As data recovery experts, we strongly say that this method is not practical and most of the time fails. There are many reasons behind this, let’s discuss them.

  • Windows Live Mail has been officially discontinued by Microsoft in 2017. So finding a safe installation file today can expose your PC to severe malware attacks.
  • The Windows Live Mail is an outdated 32-bit application. Whereas modern versions of Microsoft Outlook are 64-bit. These are two different architectures that cannot communicate.
  • The DBX to PST export process almost crashes halfway every time throwing a MAPI error or displaying that “There is no default mail client.”
  • In this approach, there is a high risk of permanent data loss as if the process stops in between, the original DBX files will become permanently orphaned or deeply corrupted.
