<# 
.SYNOPSIS
    Find active Skype for Business services on the entire tenant using Microsoft Graph.

.DESCRIPTION 
    Find active Skype for Business services on the entire tenant using Microsoft Graph. Generates an array containing the detected user and license and displays it on the screen.
    It also saves the same data in a CSV file within the folder from which you are launching the script (Current Directory in PowerShell) that can be used for later manipulation of users and licenses (and active Skype for Business plans).
    You can execute this script without parameters and wait for results.
