On Thunderbird 68.11.0(32 bit) under my main email account i had a few folders set up where i used to save the appropriate emails to like for eg , car folder would contain any emails about my car. So now i have set up a new email address which will now be come my main account , so is it possible to transfer these folders and have them showing under the new email account rather then show under the old email account , if so how do i do this
