Color categories allow you to easily identify and group associated items in Microsoft Office Outlook.
Assign a color category (color category: A keyword or phrase with an associated color that helps you keep track of items, such as messages, contacts, and appointments. You can use color categories to easily find, sort, filter, or group items.) to a group of interrelated items — such as notes, contacts, appointments, and e-mail messages — so that you can quickly track and organize them. You can also assign more than one color category to items.
Choose from a set of default categories or create your own, and then assign the
categories to your Outlook items.

Color adds visibility to your Outlook items. After you associate a color with a color category and then assign the color category to different yet related items, the
items are easier to identify and organize. For example, you can keep track of all the meetings, contacts, and messages for the Morris project when you create a category named Morris Project and assign items to it.

Color categories connect related Outlook items for easy identification. Here, with the color category displayed in the header of an open item and in the Calendar, you can see that both items pertain to the Morris Project.
Color categories are
prominently displayed in table (table: A view type that displays a list of items (rows) and their attributes (columns). Use this view to display details about items. Table is the default view type for Inbox and Tasks.) views, such as your Inbox, and within the open items themselves. The default set of six color categories is designed to be customized. You can rename the categories to something more meaningful to you or choose different colors for the categories. Beyond these six, you can create as many more color categories as you need, and you can assign multiple color categories to items as well. This flexibility enables you to design a color category system that fits your personal work style.

Color categories enable you to quickly scan and locate related items.
You can also choose a Quick Click category (Quick Click category: A default color category that is assigned to an item when you click the Categories column for the item in your Inbox or other table view. You set this color category from the Categorize menu.) that allows you to click only once in your Inbox or other table view to assign a default color category to a
Microsoft Office Outlook item. Find out more in Assign a Quick Click category below.
To make finding your categorized mail items easier, a Categorized Mail
Search Folder has been added to Search Folders in the Navigation Pane (Navigation Pane: The column on the left side of the Outlook window that includes panes such as Shortcuts or Mail and the shortcuts or folders within each pane. Click a folder to show the items in the folder.) and provides a view of all your categorized mail items. Within this folder, you can sort and group the categorized items. You can also create additional Category Search Folders for specific categories.
