Yes, you can convert Thunderbird emails to PST without Outlook by using a professional Thunderbird (MBOX) to PST converter. Thunderbird stores emails in MBOX format, and specialized tools can read these files directly and convert them into PST without requiring Outlook to be installed or an active Exchange connection.

How it works (without Outlook):

1. Install a reliable ATS MBOX to PST Converter.

2. Add your Thunderbird profile or MBOX files.

3. Preview emails to verify data.

4. Choose PST as the output format and start the conversion.

This approach preserves folder hierarchy, email metadata (To/From/Date), and attachments, supports bulk conversion, and handles large mailboxes efficiently. It’s the safest and fastest option for users who want a standalone conversion without Outlook dependency.
