Your next step should be to read through Chapter 26, "Learning Basic Outlook Techniques" to acquire the common skills you'll need for working with any of the types of information managed by Outlook. You can then move on to Chapters 27 and 28, which teach the techniques for working with each of the specific kinds of information (messages in the Inbox folder, appointments in the Calendar folder, contact descriptions in the Contacts folder, and so on). In Chapters 27 and 28, you can focus on just those sections that cover the types of information you want to work with.
Some of the instructions given in Chapter 26 will be more meaningful after you've started reading Chapters 27 and 28 and have begun working with the individual folders. So you might find yourself flipping back and forth between these chapters— don't worry, that's how they were designed to be used.
Because Outlook is so replete with features and options, the Outlook chapters (25 through 28) can't discuss them all. To assist you in locating additional information, the text includes references to specific books within the Outlook online Help system. To access a particular book, you'll first need to turn off the Office Assistant if it's currently enabled. (To do this, click the Assistant, click the Options button in the Assistant's dialog box, and deselect the Use The Office Assistant option.) Then choose Microsoft Outlook Help from Outlook's Help menu, and click the Contents tab within the Microsoft Outlook Help window.
