Architecture of the Outlook PIA
Office 2013 and later
The Outlook Primary Interop Assembly (PIA) fully supports developing against the Outlook object model in managed code. However, when you look at the PIA in an object browser for the first time, you may be surprised by the many extra interfaces that the PIA contains, and the fact that not all method, property, and event members of an object are exposed by the same object interface. The topics in this section describe guidelines for how to access object members in code, and where to look for help for objects, methods, properties, and events.
