Your post makes no sense.  Do you have the preferred account configured in
Outlook?  Does it work when using the Test Account Settings in the account
setup?  If not, what error message(s) do you receive?  What type of account
is this?  If Yahoo! or Hotmail, you must have a paid account.  If gmail, you
need to read the instructions on their site to configure it.

Outlook can be configured for multiple accounts so your inital statement
makes no sense.
