A lot of people who convert from Microsoft Outlook to Mozilla Thunderbird want to know if they can migrate their old emails without having to install Outlook. This happens a lot because Outlook makes PST files, and Thunderbird doesn’t support them directly. The good news is that there are ways to import PST emails to Thunderbird without using Outlook, both with manual methods and with professional tools.

This article will break down the process into easy-to-follow steps so that even people who aren’t tech-savvy can move their data.

How to Understand PST and MBOX Files

Knowing what PST and MBOX are before getting into the methods is helpful.

• Personal Storage Table is what the abbreviation PST stands for. This file format was developed by Microsoft Outlook to store mailbox information, including emails, contacts, and calendars.
• MBOX files can be read by Thunderbird and a lot of other email apps. It keeps a lot of emails in one text file.

Because Thunderbird utilizes MBOX and Outlook uses PST, you need to convert or extract the emails into a format Thunderbird can open.

Can You Import PST into Thunderbird Without Outlook?

Yes, it is feasible; however, it’s not as easy as just dragging and dropping the file. PST is a proprietary format, which means that Thunderbird can’t open it natively. To make the process easier, you need to either use a manual workaround or a special converter tool.

How to Manually Import PST Emails to Thunderbird Without Using Outlook
Thunderbird does not have a built-in way to open PST files without Outlook. But you can try a few manual methods. Remember that these procedures could need some extra steps and time.

Method 1: Use free email software that can open PST files.

You can import PST files outside of Outlook and then export them to MBOX using some older or open-source email clients. This can be seen in the Evolution email tool for Linux. The steps are:

• Install Evolution on your system.
• Start the software and look for the option to import mail.
• Choose your PST file and finish the process of importing it.
• Export the PST emails in MBOX format once they are in Evolution.
• Activate Thunderbird and utilize the ImportExportTools NG add-on to import the MBOX files.

This method works, but you have to install another email client, and it could take a while if your PST is big.

Method 2: Using Google Takeout as a roundabout method

You could also sync your PST emails to a Gmail account and then send them to Thunderbird.

• Get the PST file open in any free viewer or PST-compatible tool.
• Use IMAP to move or copy the emails to your Gmail account.
• After you’ve moved all your emails to Gmail, you may utilize Google Takeout to download them as MBOX files.
• Add the MBOX files to Thunderbird.

This approach doesn’t need Outlook, but it can be slow if you have a lot of emails because it takes time to upload and download them.

Method 3: Getting Help from a Friend or Coworker

You can ask someone you know who has Outlook to open your PST and export it as MBOX with an add-on or program if you don’t have Outlook. After that, you can add the MBOX to Thunderbird on your own. This doesn’t fix the problem directly, but it means you don’t have to install Outlook on your computer.

Problems with manual methods

Manual approaches can work, but they do have certain problems:

• They can take a long time and need to be done in several steps.
• It could take hours to process large PST files.
• It is possible that the formatting or attachments of an email will be lost.
• You might need to install more software or ask someone else for help.

Many people choose to utilize a professional PST to MBOX converter instead because of these problems.
