Outlook Error Protocol: SMTP, Port: 25, Secure(SSL): No, Error Number:0x800CCC0B
You may receive this error in your email client settings at some point. In Outlook this is a bug and can usually be resolved by restarting your email client and making sure you have SMTP authentication enabled.
This is not a server problem and is caused by a miconfigured email client, ISP's blocking access to port 25 or a DNS problem with your ISP.
To confirm that the mail server is online and responding you can perform the following:
From the 'Start' button click 'Run'
Type in 'telnet yourdomain.com 25'
