Live Mail 'From' address list not showing Yahoo email addresses - but shows all others.


New Email
None of the Yahoo email addresses that are in Live Mail POP/SMTP
settings are showing on the From address list.
All are correctly set up.

Via Windows Live Mail, I can receive email from all of my Yahoo addresses,
and I can also do Reply and Send with any Yahoo emails I have received.

But none of my Yahoo addresses are showing up in my Live Mail's 'From' drop list list,
so I cannot send from my Yahoo addresses when writing new emails.

See attached screenshot (below) to see what I mean.

I use a PC and Windows 8.1

I appreciate any assistance that can be offered.
