can't send emails via outlook.
I get this error. Everything has been working for a year on this notebook computer, including sending emails. But for the past week, my outbox isn't sending. When I went into mailbox settings smtp.ch3.comcast.net, , but now I get "Send test e-mail message: Outlook cannot connect to your outgoing (SMTP) e-mail server. If you continue to receive this message, contact your server administrator or Internet service provider (ISP)."
I can send emails via android phone and web portal. Any suggestions?
my email is firstname.lastname@example.org
