During the course of your day, you probably have contact with many people, including business contacts, co-workers, family, friends, colleagues, customers, and others. For each individual, you need to know key information, such as the contact's e-mail address, phone number, mailing address, fax number, and so on. To help you keep track of all this information, you can use Outlook's Contacts feature. With this feature, you can create contact records with as much or as little information as you need for that particular contact. This part explains how to organize contact information.
