Identifty different features usage for SPLA report automation

Hi,

We are trying to automate SPLA report automation using PowerShell for exchange server 2013, and need to understand few things for this purpose.

Can please someone explain what are these features, and how to identify them using powershell (whether some exchange users using them or not):

-- Shared Folders

-- Shared Address Lists

-- Shared  Contacts

-- Shared Calendar

-- Mobile Browse

-- Compliance Management

-- Exchange 2013 Anti spam

as written in this document.
