The Exchange Web Services (EWS) Managed API provides strongly typed classes that represent specific item types in a mailbox store. These item types include email messages, contacts, post items, tasks, and calendar items.

Users typically work with a class that derives from the Item class instead of an instance of the Item class itself. One exception to this is the ItemCollection class. When you work with the ItemCollection class, you might work directly with instances of the Item class. In that case, you should implement logic that determines the type of item in the store that the instance of the Item class represents. To work with that item, you should bind to the item by using an instance of the class that represents the item.
