Categories provide you with a way to organize your items. You can assign a category to any item, including contacts. You create and add categories and can give each category an identifying color. The colors display in the Item List and in the Calendar.
You can assign more than one category to an item, and specify which category is the primary one. The color of the primary category will be used to identify the item.
When you reply to an item that has been assigned a category, the same category (or categories) is assigned to the reply message.
Four default categories (Follow-Up, Low Priority, Personal, and Urgent) are available for you to immediately assign to items. You can modify and delete them if you choose, as well as continue to create new categories.
You can filter on categories by using the Show menu next to the Filter icon. You can add a Category column heading and sort your Item List by category.
