There are many occasions where I need to refer back to emails that I've received from someone, and my response to them, maybe a month or so ago.  I go to the Sent Folder and select the To option.  However, when I look at a particular person's emails, the dates are in no particular order and it takes me lots of time to find the email I need.  How do I get the emails in the To option to be sorted in date order?
