You can now quickly switch between your favorite folders without opening the full folder pane. When the pane is collapsed, your favorite folders appear as a vertical list, giving you one-click access to the folders you use most. Each folder shows unread or total counts so you always know what needs attention. Right-click any favorite for the same options you're used to, and your selections stay put across sessions. It's a familiar experience for anyone who loved favorites in classic Outlook, now built right into the new Outlook. #newoutlookforwindows
