I have a number of contacts for which I only have a name and a phone number.
I use these for my cellphone normally, but they are included in my Windows
contacts folder. I wanted to organize my contacts so that only people that I
have an email address for, and that I normally correspond with, would show up
when I used Windows Mail to send an email. In other words, when I click the
"to" button on a new email.

I tried creating a group, but then I'm stuck sending email to everyone in
the group. I tried copying the names with email addresses that I normally
correspond with to a subfolder within Contacts, but Windows Mail insists on
just merging the contents of the subfolder with the main contacts folder when
I click the "To" button. Now I get TWO copies of the email list interspersed
with the non-email contacts.

How can I get Windows Mail to let me see and open the subfolder I created
that has only the addresses I want to use?
