On one laptop connected to a LAN the test message in Outlook fails. It presents an error message that states:
Establish network connection: Unable to connect to the internet or to the network. Please verify the connection blah, blah,blah.
I can however send and receive email and internet access is fine. Mighty strange! I have 4 different email accounts on this laptop so the test feature is something that comes in handy when I suspect a problem. I dropped the firewall and email scanner (AVG Network Edition) but it does not make a difference.
