Problems sending emails from sub account

[Mick Young]

We are running Vista. I have just set up two email sub accounts. One for my
wife and one for me. Previously our main default email address has been used
for both me and my wife and was set up in my user account which is also the
administrator account. We want separate email addresses. My wife has a
separate user account and I set her new email address whilst logged in to her
user account. Her address works perfectly well when she is logged in to her
PC user account. I have set up my email address as a secondary address in my
administrator account and created a sub-folder under inbox and am directing
all emails to this box using email rules.
When I try to send emails from this box they fail to send; I get an error
message. I notice also that the 'From' address is the default address. This
suggests to me that I have done something fundimentally wrong. Any
suggestions, or instructions as to the correct way to set up a secondary
email address.

The error message I get is:

The message could not be sent. The authentication setting might not be
correct for your outgoing e-mail [SMTP] server. For help solving this
problem, go to Help, search for "Troubleshoot Windows Mail", and read the
"I'm having problems sending e-mail" section. If you need help determining
the proper server settings, please contact your e-mail service provider.

The rejected e-mail address was '(e-mail address removed)'. Subject 'test',

Make sure you have send authentication enabled.
Go to Tools, Accounts, select that account, Properties, Servers.
Enable the "My server requires authentication" option.
