How do I change the font size in Windows Live mail 2012 message list-win 8.1

I have been through the forums, chatted with a tech, called windows support, and now back where I started-very disappointed in Microsoft help, so far.All the solutions are for live mail 2011, and do not work with 2012. Whatever the answer tech directed me to I had already tried, and did not work. Changing to using just plain text mail is not a workable solution for me.Going through the view/read menu and changing text size has no effect on the message list or any other part of the screen. This seems like it would be an easy fix-or am I the only one who has this problem? I did not have this issue in win 7,live mail 2011. Thanks for any help anyone can offer.
