One of the most popular email programs is Microsoft Outlook, which includes all information, such as contacts, calendars, tasks, and emails, stored in the PST file (Personal Storage Tables). Although PST works flawlessly with Outlook, it is incompatible with Thunderbird, Apple Mail, and Eudora, among other email programs. Because these email clients usually accept the MBOX format, users must convert PST File to MBOX. 

We’ll go over the best methods for successfully exporting and converting Outlook PST file data in this blog. Understanding how to convert PST to MBOX format is crucial, regardless of whether you are permanently switching platforms or want a safe backup.

Why Export PST File to MBOX?

The reasons why users would like to switch are several:

  1. Cross-Platform Compatibility: MBOX can be read across a broad number of clients, as compared to PST, which includes Thunderbird, Apple Mail, Entourage, and SeaMonkey.
  2. Increased Accessibility – Many users love MBOX because it has a simple architecture and is supported in all systems.
  3. Platform Migration – Upgrading Outlook to Thunderbird or Apple Mail- requires conversion PST to MBOX so that accessing the information is made a lot easier.
  4. Backup& Archiving –MBOX is small, easier to manage for archiving.

Obviously, it is beneficial to convert PST to MBOX  as it enhances the performance and functionality of your crucial email data.

  1. Open Outlook, then select File > Open & Export > Import/Export.
  2. Choose Outlook Data File (.pst) under Export to a File.
  3. Save the exported PST file to your system.
  4. Now, use IMAP (like Gmail or Yahoo) to sync Outlook with another email client such as Thunderbird.
  5. Export the synchronized mailbox from Thunderbird in MBOX format.

This is a workaround that indirectly helps to convert PST file to MBOX, but it requires extra syncing steps and time.
