Mozilla Thunderbird is a popular, free, and open-source email client used by millions worldwide. But what if you need to move your emails to a different email client, back them up for safety, or save them in another file format? That’s when exporting your Thunderbird mailbox becomes essential. The good news is, you can export all Thunderbird emails — either manually or using a professional solution.
Why Do You Need to Export Emails from Thunderbird?
There are many reasons why users choose to export all their Thunderbird emails, including:
✅ Data Backup: To keep a safe copy of your entire mailbox in case of accidental deletion or corruption.
✅ Email Migration: When switching to another email client like Outlook, Apple Mail, or web-based services like Gmail.
✅ Free Up Space: To archive old emails and lighten your mailbox for better performance.
✅ Legal and Compliance: To store important communications in formats like PDF or PST for audits or legal records.
Whatever the reason, having an export copy gives you peace of mind and complete control over your emails.
How to Download All Emails from Thunderbird Manually?
You can manually export emails from Thunderbird using the ImportExportTools NG add-on. Here’s how:
1️⃣ Install the Add-On:
Open Thunderbird and go to Tools > Add-ons & Themes.
Search for ImportExportTools NG, download, and install it.
Restart Thunderbird.
2️⃣ Export Emails:
Right-click on the mailbox or folder you want to export.
Go to ImportExportTools NG > Export all messages in the folder > EML format (or choose MBOX if you want one file per folder).
Choose the destination folder on your computer and save.
🔔 Note: This method works well for small mailboxes, but it can be time-consuming if you have many folders or need to export the entire profile with attachments intact.
