Unable to configure Email on Outlook

Our office server uses Windows Mail. I have set it up and I get all my incoming emails just fine. However, I keep getting an error message about POP and SMTP server, and I'm cannot t send out any messages. I have set it up to use Cox's SMTP server (smtp.pop.west.cox.net). Please see below image.
Is my SMTP setting correct? Do have any suggestions on how to make it work?
Thanks.
