There are many free tools available to import MSG to Thunderbird, but they can only convert small batches of MSG files and have a chance of data loss. That’s why I suggest you try the Softaken MSG to MBOX Converter since Thunderbird support MBOX format. With this tool you can quickly convert MSG files into MBOX format with attachments. It has no file size limits also it convert batch MSG files into MBOX at once. It guarantees that during migration no data loss will occur.

That's a huge time-saver for managing emails! Finding the right bulk tool is like our family's trust in the snow day calculayor every winter. Instead of manually checking every weather report, we get one clear, accurate prediction that saves us from all the guesswork and stress. A good import tool does the same—it efficiently handles a tedious, repetitive task in one go, giving you a reliable outcome and freeing up your time for what really matters.

One of the main challenges when transferring a sizable collection of MSG emails to Thunderbird is that Thunderbird does not handle MSG files at all. Converting the MSG files to MBOX format is the best option to get around this restriction. DataVare MSG to MBOX Converter is a dependable solution for this. It is made to handle large amounts of MSG data and export it into clean, import-ready MBOX files. During the conversion, this application ensures that nothing is lost by preserving your attachments, headers and formatting. The process is made simple by its user-friendly structure and you can test it out for free to see whether it suits your needs.
