Requested re-entry of correct password is not accepted either. I can however log on to Outlook on line through Firefox and connect using the correct password. I have changed nothing in any settings, and the correct password is still stored in Thunderbird settings.

Thanks Corey, worked like a dream. If it was so simple, I am left wondering why Microsoft, with all their available resources, were not able to advise their clients what was going on......... The answer, of course, is obvious. Bazza.
