Just importer a few thousand emails from another program into Thunderbird.. Looks like if I drag and drop a business address from the personal address book into a new folder I created called "Business" and then delete the email listing in the personal address book... the listing in the "Business" folder deletes, too... Surely to god there's a way around this without having to type in all the information for each business and then save it in the Business folder.. (I have over a hundred with extensive notes..) Basically I'm asking if there is a simple drag and drop technique to do this.
