  • I am using Mozilla Thunderbird for managing my emails, but I recently discovered that Thunderbird does not natively support exporting emails in the MSG format. I need to export emails to MSG files for backup and compatibility with other applications like Outlook. What is the best workaround or method to export emails from Thunderbird to MSG format efficiently? Are there any reliable third-party tools or methods that can help accomplish this without losing email metadata?

  • There is a way to convert Thunderbird files to MSG files. If you want to get started, the WholeClear Thunderbird to MSG Converter is what you need. Along with having users export a lot of Thunderbird files to MSG format with attachments. A free demo pack is available for the program. Users can use it to see how the program works and what it can do. People who only need to convert their email address a little bit will find this choice very helpful. It works with all versions of Outlook, including 2003, 2010, 2013, 2016, 2019, 2021, and more. It is also able to work with all versions of Windows.
