To import Outlook PST files into Thunderbird, you can choose between manual methods and automated tools. Here’s a structured guide on how to proceed.

Manual Methods​

Method 1: Using Outlook and Thunderbird Together​

If both Outlook and Thunderbird are installed on the same machine, follow these steps:
  • Go to Control Panel > Programs > Set your default programs.
  • Select Outlook and click Set this program as default.
  • Open Thunderbird.
  • Click on the Menu button, then go to Tools > Import.
  • Choose Mail, select Outlook, and click Next.
  • Follow the prompts to complete the import process.

Method 2: Convert PST to MBOX​

Since Thunderbird does not support PST files directly, you can convert your PST files to MBOX format, which Thunderbird can import:
  • Use a conversion tool (like MailStore Home or a PST converter) to convert PST files into MBOX format.
  • In Thunderbird, go to Tools > Import, select the MBOX files, and complete the import.

Automated Methods​

Method 1: Using Outlook PST Converter Tools​

Using dedicated software can simplify the process significantly. Here’s how:
  • Download and install the Cigati PST Converter Tool.
  • Run the software and select the PST file(s) you want to import.
  • Choose Thunderbird as the output format.
  • Start the conversion process, which will directly create an MBOX file compatible with Thunderbird.

Method 2: Google Takeout (if Gmail is set up in Outlook)​

If you have configured Gmail in Outlook, you can use Google Takeout:
  • Drag emails from Outlook into a Gmail folder.
  • Use Google Takeout to download those emails.
  • Import the downloaded emails into Thunderbird after setting up your Gmail account in it.

Conclusion​

While manual methods are possible, they can be cumbersome and may require technical knowledge. Automated tools provide a more straightforward solution for importing PST files into Thunderbird efficiently and with less risk of data loss.
