Double check your settings for the server in outlook.
SMTP needs to be port 25, POP3 110 - you don't want the SSL box ticked.
To check you can access the servers, try the following
Click start, run, and type in CMD and press enter.
type
telnet pop3.demon.co.uk 110 and press enter
You should get a message like
+OK demon POP3 server ready (demon.co.uk)
type quit and press enter
Now type
telnet post.demon.co.uk 25 and press enter a few times
You should get something appear, entering quit and press exit should get you out.
If you cant see the servers with the telnet commands, you have a router/firewall/antivirus/virus problem
