I cannot find the place in Outlook 2003 (Windows XP Pro is the OS) where I can change the font style, color and size for how group headings are displayed in an e-mail view that is grouped by something - By Subject, or By Sender, etc. Is this functionality in Outlook and if so where? Or is it in Windows Themes or Schemes or whatever, and if so where?

Much thanks for help. I don't like the way OL 2003 looks now - not enough difference visually between what's read and what's not read, the color is gray, and so on.
