I booted windows 11 in safe mode with networking. I still get Outgoing server can't be reached message and it times out. I had no problem using Thunderbird on my old computer running windows 10. Even donated. mail.twc.com is the outgoing SMTP server as is the incoming which allows me to receive. Windows Mail is my only option to use now. Its outgoing is mail.twc.com
