Hi

i've been using Thunderbird for years to send and receive emails but not any more. I only get "Authentication failed, write new password" I have been told that this is because Office365-account uses "modern authentication" and no longer supports POP3- or IMAP-connection; I could only use email-application with Exchange-connection. Is there any way to get back using Thunderbird?
