Views

Views are covered in detail in Chapter 3, Administering Azure Active Directory, so we won't delve too deeply here. 

There's a default view that shows all users. If you have a small company, that might be fine. As soon as you have a large number of users (or accounts, such as service accounts that were assigned email addresses, external contacts who were invited as guest users, former employees, special-purpose administrator accounts, and so on), the list can get unwieldy. You may want to use one of the other default views, or create one of your own. See Chapter 3, Administering Azure Active Directory for more information on how to do this.
