I must move all my personal emails from my Thunderbird email on my work PC to my personal Thunderbird email on my MacBook. I would like to combine them and have access to all at once. I have moved all my personal emails on my work PC into one folder labeled “Personal.” I would be ok moving the personal emails to the local TB drive on Mac if recommended. All I can seem to find when I search the knowledge base is how to move Thunderbird from old to new. And in those instructions they overwrite the profile on new. I am already actively using Thunderbird on my Mac so what I must do is merge pc TB to Mac TB but I have not been able to find instructions. It’s been a long time since I’ve been on a Mac so I’m re-teaching myself. I’m much more fluent on the PC right now. For me there is nothing that compares to Thunderbird. I’ve been using TB for 25 years and have not found anything that compares. Thank you for you assistance!
