Is it possible to convert PST files to Thunderbird format without Outlook?

[mariya234]

If you want to open or import a PST file (created by MS Outlook) into Thunderbird without using Outlook, there are two ways you can do this:

Method 1: Manual Way (Free, but a bit tricky)​

Thunderbird doesn’t support PST files directly. So, you’ll first need to convert the PST file to MBOX or EML format, which Thunderbird can read.
Here's a basic idea of how it works:

1. Use a free tool (like ReadPST on Linux) to convert PST to MBOX.
2. Then open Thunderbird and install the ImportExportTools NG add-on.
3. After that, go to:
   • Tools > ImportExportTools NG > Import mbox file
   • Select the converted file and import it.

Note: This method doesn’t always work perfectly, and it might take time if you have lots of emails.

Method 2: Easy Way Using DRS Softech PST Converter Tool​

If you don’t want to go through all that hassle, the DRS Softech PST Converter Tool makes it super simple.
