You could try setting up Windows Mail with the following settings:
Outgoing Server (SMTP) smtp.mail.yahoo.co.uk (or .com)
Incoming Server (POP3) pop.mail.yahoo.co.uk (or .com)
Use your email address & password as normal & make sure your set for 'outgoing authentication'
I'm not 100% sure as i've not used Windows Mail in a while but it might be worth a try.
Hope this helps
