Cannot receive or send in Outlook

I use Outlook for email. It has just started acting up by giving me an "Operation Failed" error message when I press the Send / Receive button. I have tried the "repair" tool with no luck. I have reset and checked the email accounts and there is no problem with sending test messages. I have checked all the settings and they appear to be fine. It is only on one of my computers that are networked through a router hooked up to the same incoming cable connection. I'm out of ideas. Does anyone have a fix for this maddening problem?

 

Check your firewall settings on the PC and if its on turn it off, your router has a firewall. Also you can try to use the IP address of the server instaed of the name. To get the IP just ping the server name, you will need to do both pop and smtp servers.

Example: if your server is pop6.sympatico

Click START, RUN type CMD
At the prompt type "ping pop6.sympatico.ca"

Look at the results the ip will be there, type this into the server name in your account properties.
