.SYNOPSIS
	Enable or disable service plan options within each license package while respecting current configuration for each user.
.DESCRIPTION
	Even when using PowerShell, Microsoft doesn’t make it simple when it comes to adjusting licensing in bulk and service plan 
  options/apps within. Mainly that is because there is no easy way to keep a current configuration – 
  any license change you apply to a user overwrites their existing setup. 
  To address that letdown I created a script you can find below.
.WARNING
  This script assumes you are already connected to the right services and have all modules installed.
