I have been using Thunderbird for many, many years. For last about 4 days , after updating to Version 91.6.0 , I I cannot send emails using my IMAP hotmail accounts I am on Windows 10. The error message is: “Sending of the message failed. The message could not be sent because connecting to Outgoing server (SMTP) smtp-mail.outlook.com failed. The server may be unavailable or is refusing SMTP connections. Please verify that your Outgoing server (SMTP) settings are correct and try again.” I have tried multiple suggestions in the forum but not successful – please help. Thank you
