I recently found several archived MBOX files from Thunderbird backups and needed a simple way to open and convert them without losing attachments or folder structure.
Manual methods worked for small files, but handling multiple mailboxes became time-consuming. I later tried BitRecover MBOX Converter Wizard for bulk conversion, and it was easier to manage large email archives.
I’m curious to know what methods or tools other Thunderbird users here prefer for managing or converting old MBOX files?
