Why Move Outlook Emails to Thunderbird?

Moving Outlook emails to Thunderbird is necessary for several reasons, depending on individual preferences or organizational requirements. Here are some common reasons why people choose to import PST files to Thunderbird:

• Outlook is part of Microsoft Office, which usually requires a paid subscription or license.  On the other hand, Thunderbird is completely free and open-source.
• Thunderbird runs on multiple platforms, including Windows, macOS, and Linux. If users are transitioning to a different operating system, Thunderbird might be more suitable.
• Some users find Outlook’s extensive features overwhelming if they only need basic email and calendar functions.
• Thunderbird is generally less resource-intensive compared to Outlook, making it a good option for older or less powerful computers.
• Thunderbird supports various extensions and plugins that offer niche features not available in Outlook.

How to Import Outlook to Thunderbird

If you’re planning to move emails from Outlook to Thunderbird, you’ll need to convert the Outlook PST file to a format that Thunderbird supports, such as MBOX. Tools and methods like third-party converters or intermediate IMAP syncing are often used for this. So, it’s not always as simple as clicking a button to transfer emails from one to the other. But don’t worry—the upcoming section will help you to move Outlook emails to Thunderbird successfully.

Technique 01: Import Outlook Emails to Thunderbird Using Outlook

Outlook uses the .pst file format, but Thunderbird doesn’t support .pst files directly. So, the first step is exporting the emails from Outlook.

Step 01: Export the PST File from Outlook

1. Open Microsoft Outlook.
2. Click on File in the menu and select Open & Export.
3. Choose Import/Export from the options.
4. In the wizard that opens, select Export to a file, and then click Next.
5. Choose Outlook Data File (.pst) and click Next.
6. Select the email folders you want to export (e.g., Inbox, Sent Items, etc.). If you want to export everything, select your account name at the top.
7. Choose the location where you want to save the .pst file, give it a name, and click Finish.

Now you have a .pst file containing your Outlook emails.

Step 2: Convert PST to MBOX Format

1. Download a reliable PST to MBOX converter tool.
2. Launch the tool and add the PST file you exported in Step 1.
3. Select the conversion option to MBOX format.
4. Choose a destination folder for the MBOX file and initiate the conversion.

Step 02: Import PST Files to Thunderbird

1. To import PST Files to Thunderbird, launch Thunderbird first.
2. Go to the “Tools” menu, then select “Import” and choose “Mail“.
3. Pick “Outlook” from the options and press “Next“.
4. Locate the .mbox file you previously exported from Outlook and click “Next“.
5. Choose the items you wish to import (typically “Mail,” but you can also select “Address Books” and “Settings” if needed) and click “Next“.
6. Click “Finish” to complete the import process.

Technique 02: Built-in Feature of Thunderbird to Import Outlook to Thunderbird

Thunderbird offers a built-in feature to import data from other email programs, including Outlook. Here’s how you can use this feature to import your Outlook data to Thunderbird:

• Launch Thunderbird on your system and navigate to your dashboard.
• Next, select the “Import” option under “Import from Another Program.”
• Choose “Import from Outlook” and click the “Continue” button.
• The process may take some time as it transfers all Outlook accounts to Thunderbird.

If this built-in method doesn’t meet your needs, you can also consider using the professional tool or exporting your Outlook data to a compatible format like MBOX for easier import into Thunderbird.
