Need help importing hundreds of MSG emails into Thunderbird
Quote from henrywalker on June 5, 2026, 4:58 amI recently changed jobs, and my previous employer provided me with an archive of my work emails before deactivating my Outlook account. The archive contains hundreds of MSG files, and now I need to access them through Thunderbird.
The challenge is that Thunderbird doesn't recognize MSG files natively. I managed to convert a few manually, but repeating the process hundreds of times is unrealistic. I also noticed that some manual conversion methods don't always preserve attachments or metadata correctly.
I've been researching how to Open MSG File In Thunderbird without losing important information. Many tutorials mention converting the files to EML and then importing them into Thunderbird using add-ons. While that works in theory, it feels unnecessarily complicated when dealing with a large volume of messages.
While browsing forums and migration discussions, I repeatedly saw recommendations for the DRS Softech MSG Converter. Users claim it simplifies the process and supports bulk conversion, which sounds useful for situations like mine.
Has anyone here handled a similar migration? I'd love to know what worked best and whether there are any hidden issues I should be aware of before converting a large email archive.
