Color categories allow you to easily identify and group associated items in Microsoft Outlook. Assign a color category to a group of interrelated items—such as notes, contacts, appointments, and email messages—so that you can quickly track and organize them. You can also assign more than one color category to items.

You can choose from a set of default categories or create your own, and then assign the categories to your Outlook items. The category colors are displayed in your Inbox, and within the open items themselves. You can rename the categories to something more meaningful to you or choose different colors for the categories. This flexibility enables you to design a color category system that fits your personal work style.

Note: If you are using Outlook with an IMAP account, you cannot assign categories to an item. The IMAP email account type does not support categories.
