Outlook unable to send emails
I am using Outlook 2013 on a Surface running Windows 10. The error message I get when testing send message is: 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).
My Outlook email box is configured to use POP3 (port 110) and SMTP (port 25). My username and password are specified for both receiving and sending.
When I use the same settings on my Sprint cell phone network, Outlook works just fine. I therefore assume this is a Cox configuration issue. If you need additional information, just ask, as I am in IT professional, and am willing to work with you to resolve this issue. Please advise.
