You can try to import .MSG files into Mozilla Thunderbird, you can use the Aryson MSG Converter. This tool converts MSG files into Thunderbird-compatible formats like MBOX or EML. Simply install the software, select your MSG files or folder, preview the emails, choose MBOX as the saving format, and convert. Once converted, open Thunderbird and use the ImportExportTools NG add-on to import the MBOX files. This ensures that email content, attachments, and metadata are preserved. The software supports batch conversion, date filtering, and removes duplicates, making it efficient for large-scale email migrations to Thunderbird on Windows systems.
