I want to delete emails but Mozilla Thunderbird will not allow me to do this. It keeps sending a message "There is not enough disk space to download new messages. Try deleting old mail, emptying the Trash folder, and compacting your mail folders, and then try again." I am trying to delete old emails and it sends me a message to "try deleting old emails." So frustrating!!!! It is telling me to do what I am trying to do but is stopping me from doing just that!!!! NOT HAPPY!!!!!
