Emails Received And Sent To Be Sorted Based On Date Received And/or Sent

My Microsoft Mail in Vista moves received and sent emails in a very odd manner. Rather than keep emails sorted strictly by date received and/or sent, the emails are moved. For example, if I reply to an email received and it had a subject line, a return email may be buried deep based on who sent the original and the subject. This makes finding the emails very difficult. I would like all emails received and sent to be sorted based on date received and/or sent, similar to Outlook.
