The New Outlook Gains Colored Folder Icons

Colored folder icons doesn't seem like a new feature that should appear in an email client that's been around for a long time, but the new Outlook for Windows and OWA now both offer users the ability to choose different colors for folder icons. Apparently, this is an important step forward in the development of the new Outlook and might just be the killer feature to convince the curmudgeons who use Outlook classic to switch.
