Hi there, I have looked for hours on your site on how to get thunderbird sending emails, I have attached this to my outlook account and used all the correct IMAP/Port/Server settings that are displayed. For some reason when I go to send an email, it says to me that "login to server smtp.office365.com with username ****myusername**** failed" THEN it says "Unable to authenticate outgoing server (SMTP). Please check the password & verify the 'Authentication Method' in account settings, Outgoing Server (SMTP)" I have done all the above multiple times, I have even tried other settings, and it STILL DOES NOT WORK. I would greatly love some help with this as it is now becoming very tasking and frustrating. Please can someone help me out ASAP as I would love to start making use of Thunderbird. Thanks - Max!
