‘My system is loaded with corrupt PST files. I wishfully want to export PST to MBOX  using a secure method. Is there a possible way to resolve this’.

The difference in file formats is a long term issue. It is considered a problem because each file format supports a distinct Mail client. If the file format mismatches the specification of a mail client, then that extension file certainly can’t be accessed. To prevent such an issue, one needs to convert the file extension into another. Here, we are going to look at the methods to export files from PST to MBOX with the help of various approaches that include manual as well as professional solutions.

However, the migration process depends on what kind of operating system the user has. If the user has a Mac operating system then he/she must use the First Approach. Likewise, if the user has a Windows operating system, then the user must use the Second Approach. Moreover, if both the approaches don’t give out satisfactory results, then you should use the third-party software for Outlook PST file conversion.

Now, let’s look at the profound ways to convert  PST files into MBOX format using the 3 best possible approaches.

3 Methods to Convert PST to MBOX Thunderbird

  • Now, hit the radio button next to the ‘Mail’ option from the dialogue box and then press Next.

  • Then, relaunch Thunderbird, and you will be able to view all the folders containing Outlook data. Redirect to the Tools menu -> tap ImportExportTools -> hit Export folder (.zip) and pick an appropriate location for the file.
