It is so very very frustrating that thunderbird won't send my email and consistently asks me to enter my password. Each time I do that does NOT solve the problem. I've tried all the solutions I found on your site and others and nothing works. I do NOT want to switch email clients, but this is ridiculous and is not making things easier. I thought I'd switch from Outlook, but this is worse than the issues with Outlook. I really wish you would fix this once and for all. It appears this has been happening for well over a year. Please advise.
