Create a new color category
Color categories enable you to easily identify and group associated items in Microsoft Outlook. Assign a color category to a group of related items — such as notes, contacts, appointments, and email messages — so that you can quickly track and organize them. More than one color category can be assigned to items.
The category colors are prominently displayed in table views, such as 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.
To create a color category, do the following:
In any view, on the Home tab, in the Tags group, click Categorize, and then click All Categories.
Note For calendar items, the Tags group appears on the Appointment or Meeting tab. For an open contact or task, the Tags group appears on the Contact or Task tab.
In the Name box, type a name for the new color category.
Click the arrow next to Color, click the color that you want.
If you want to assign a keyboard shortcut, in the Shortcut Key list, click a shortcut.
Click OK on the Add New Category and Color Categories dialog boxes.
