When I installed Windows 10, Windows Live Mail continued to work as before in Windows 7 except the dates now confuse me.  They have always been displayed the logical way, Day/Month/Year but now they are displayed Month/Day/Year.  So for instance the First of March 2016 will read 3/1/2016.  In all my other communications that is today's date - the Third of January 2016.

How can I change the way the date is displayed please?
