Color categories in Outlook help you more easily recognize and organize related items. You can apply them to meetings, appointments, emails, notes, contacts, and more. 

Once assigned, the color category indication appears within the individual item and also in collective table views (e.g., Inbox). If needed, you can assign multiple color categories to a single item. You can also customize the names and colors of your available color category set. 

Note: If you apply a color category to a meeting or request that you've received from another person, the color category selection will not affect their Outlook view. Your category selections apply only to items within your calendar.
