Am trying to update both my laptop and mobile and wish to access emails on both via Thunderbird. Just bought new laptop, and downloaded Thunderbird, but when I put in current email address and password correctly, I am told it is wrong! Why can't I just speak to someone in a Customer Services department to sort it out straightaway? I bet I have the same trouble when I try to do it on the new smart phone as well! New laptop have Windows 10 on it, incidentally.
