I have been a Thunderbird user for years. I reinstalled Windows 10 on my computer in December and then installed the latest version of Thunderbird. Ever since then I have had problems receiving emails. The program kept asking for my password. and rejecting the password I entered. I went through the support forums and have done everything suggested - made sure I was using the proper SMTP settings; deleting the passwords, restarting and resetting the passwords; etc.. I can get the system functioning, but then a week or two later, Thunderbird has forgotten the passwords. I have three email accounts I use through Thunderbird, all through the same ISP, acsalaska.net. What seems strange to me is that one email account, my default account, works fine - I can receive and send emails fine. However, I keep having to reset the passwords on the other two accounts. What am I doing wrong. This has been going on for months and I am about ready to dump Thunderbird
