Problem appeared after 3 significant events:
1.  I upgraded from Vista to Windows 7.
2.  I installed Windows Live Mail, including the Outlook connector.
3.  I added a Yahoo account to Outlook using the connector.

Outlook could not connect with Yahoo.  It wouldn't stop trying.  I tried to 
close the account to no avail.  Under Tools, when I select EMail Accounts I 
receive an error suggesting I have a registry problem, that I should restart 
and, if that doesn't work, reinstall Outlook.

Restart, the Fix routine and a complete reinstallation have not solved the 
problem.  In additon to the symptom mentioned above, Outlook will no longer 
perfrom a send/receive.

Windows Live Mail , the mail client, or Windows Live, the service?

The Outlook Connector is used only for Windows Live/MSN/Hotmail.  You cannot 
connect to any other mail service with the Connector.

If you're using a yahoo.com address, unless you pay for the account, you 
cannot use Outlook to access it.
