I am using Thunderbird for my O365 Outlook, until recently gotten this msg "Login to server outlook.office365.com with username ###@###.### failed." but I can login online perfectly fine.

Here are my Server Settings Server Type: IMAP Mail Server Server Name: outlook.office365.com Port: 993 Connection security SSL/TLS Authentication method: Normal password

Outgoing Server (SMTP) Settings Server Name: smtp.office.365.com Port: 587 Authentication method: Normal password Connection security STARTTLS

Pics attached for better understanding.
