Although Outlook creates a business card for you, you are ultimately in control of what the card contains and how it looks. To control what the card includes, you open the Edit Business Card dialog box, which you can get to by clicking the Business Card button on the Ribbon in the open contact.
You can choose background colors and pictures for the card at any time. However, it's a good practice to make sure that you've got all the information in the card first. You'll learn how to get fancy in the next lesson, "Get fancy: Add some flair to your card."
