Showing the client that was used to create or update an Appointment in Exchange 2013/16 using EWS

(This property is set by the Exchange Store based on what client is being used)

 I've put together a script that aggregates this property and produces a summary report like

Its also produces an export report of all the appointments that looks like the following so you can see at the appointment level what client is being used.

I've put this script up on GitHub here https://github.com/gscales/Powershell-Scripts/blob/master/ShowCalendarClients.ps1
