I am finally closing my paid Juno account and would like to have access to all of my old emails from there in Thunderbird. Related questions have been asked before, but I think that people who have not used Juno email do not understand how it works. Thunderbird will obtain emails from the Juno Webmail site just fine. However, once you check messages using the Juno software that is on your computer, it downloads them into that and they are no longer available on Webmail. I haven't figured out a way to get those emails onto Thunderbird or anywhere else. Juno has a backup system that can save them in a single file (.jbk), which you can use to import them to Juno on a new computer, etc. This does not appear to be a type of file that Thunderbird can recognise. So my many years of old emails are stuck in Juno because their system is apparently not compatible with any other. Is there any way to move them into anything else?
