PS Script: Assign license based on AAD Security Group

So, just to make it easy, here is the Exchange Online assigning script without using it for Unlicensed Users only.

AAD Security Group Name: Exchange_Users

See earlier post for pre reqs and information.

 .SYNOPSIS
    Script that assigns Office 365 licenses based on Group membership in WAAD.
 .DESCRIPTION

#The script assigns license Exchange Online Plan 1 or 2 based on Group Membership and that the user doesn't have a license.
#It can seem abit reverse as we enable EnterPrisePack, but disables everything but what we want to keep.
#This is just the way it works when workin with Plan Packages, compared to single Plans.
