I want to transfer a large number of old emails saved in my Inbox and my Sent mail to My Book but it looks as if first I have to find something to save them onto in my computer. I have Vista 7, and all the procedures I'm finding online are using Outlook, which is not in Vista. So what procedure can I use to get those emails put on the exterior storage so that they can later retrieved? My email provider is Earthlink. I have Firefox.
