Outlook 2007 not connecting to the internet

[EBR]

I am running Outlook 2007 on Vista. It is set up as my default email
program. When I review my email profile settings from the control panel and
send a test message it sends just fine, and appears on my Blackberry so I
know it's working.
However, I can't send or receive from Outlook 2007. It times out in trying
to connect to the server.

I tried clicking on the "search the web" icon from outlook and it tells me
that I'm not connected to the internet, even though I can access the internet
when I open my browser from the desktop.

I've tried uninstalling and reinstalling Office 2007 and that didn't help.
I ran the Office Diagnostics with no errors found.

I am able to send and receive from Windows Mail but prefer to use Office
2007. Any suggestions?

Thanks
