Message that it cannot be logged in server is shown.
I am working in Japanese but this site changes to English version and I cannot ask question in Japanese. So I do not know how English words are shown but I try to translate Japanese message to English. I have been using this Mozilla thunderbird for many years and have installed in several PC's. And now I bought a new PC Win 11. I downloaded software and message like that Account setting is found in Mozilla ISP data base. I proceeded as instructed and acknowledged warning. Then message is shown like this cannot logged in server, check if username, password or setting. I renewed password but still same message is shown. I would appreciate kind help.
