The easiest way to move MSG files to Thunderbird is by converting them into a compatible format like MBOX or EML. Thunderbird does not support MSG files directly, so using a reliable tool like Aryson MSG File Converter simplifies the process. This software allows you to convert single or multiple MSG files while preserving attachments, metadata, and formatting.

First, install and run the tool, then add your MSG files or folders. Preview the emails and choose MBOX or EML as the output format. After selecting the destination path, start the conversion process. Once done, open Thunderbird and import the converted files using the import option.

This method is quick, user-friendly, and does not require Outlook installation. It is especially useful for bulk migration, saving time and ensuring complete data accuracy during the transfer process.
