Today I am going to explain three superlative free methods of exporting data from MBOX to PST format. Each user can follow the steps, however, some tactics require additional knowledge, but if you have potential then you can easily move your mailbox to Outlook.

Now first we have to take a look at the MBOX and PST file formats that are created by different email clients in your local system. Both email structures differ by body and elements.

MBOX data files only store emails and attachments while the Outlook PST file also contains contacts, calendars, tasks, etc. Therefore, some strategies are completed in two to three phases.

Reasons & Benefits of moving data from MBOX to PST

If we search for something like an investigator, there can be many reasons for it. Similarly, we have some examples of users who find ways to convert MBOX to PST for their reasons.

  1. MS Outlook is a product of Microsoft Corp and it manages user information (email, contacts, calendar, tasks, etc.) in a PST file. So it is easy for the user to combine data in a single format. However, the user can export it individually as per his requirement.
  2. Outlook can manage the data through Exchange Server, thereby preventing unauthorized access to the data and also ensures the security of the data.
  3. Microsoft launched Outlook applications on Windows and Android phones in 2015 that make it easy for a user to access data anywhere and anytime.
  4. Outlook has some outstanding features that you rarely see in other email clients: email scheduling, creating meetings/appointments, keyboard shortcuts, calendar sharing, creating rules, and more.

  • Fill in your name, email address (Gmail Account), and password carefully then hit on continue button.
  • Choose IMAP and click on the Done button.

Method 2: Use Eudora email client

In the second free method, we use Eudora which supports MBX file format (family format of MBOX). With this method, we can also export data from MBOX to Outlook PST format.

Note: This method only works in the older version of MS Outlook.

Phase 1: Setup Eudora and Paste mailbox

  • Install Eudora and configure it with any email account.
  • Go to the default location of Eudora and paste your MBOX data file.
  • Change mail format: ABCD.mbox = ABCD.mbx (both have similar data structure)

Phase 2: Move Eudora mailbox to Outlook

  • Run MS Outlook and click on the File tab
  • Go to import and export wizard >> Select “Import Internet Mail & Address


  • Choose Eudora (2x, 3x, & 4x) light & pro then press Next button
