Thunderbird stopped sending emails and I didn't change anything

What do I need to do to have my emails sent? The message said login to server smtp.office365.com with the user name car1ks@outlook.com failed. I have changed nothing and have no idea what happened or how to fix the problem. Please restore my email.
