Good morning. I have been using Thinderbird portable for years with no issues, but I now have an issue I've never had before. I have a BTinternet email address and it is now constantly asking or my password. I have remember password ticked when I put the password in. When I go to passwords in it, the passwords stored for IMAP and SMTP are correct. I have removed the passwords, restarted and then reinput passwords as asked it to save. I have removed my account and reinstalled. I have deleted the entire program etc and reinstalled and still the same problem. This doesn't happen when I use Outlook (So don't think it is my btinternet account). Any Ideas greatly received. Thanks
