Delete Outlook profile

Here is a simple script to delete Outlook profile(s) and their OST’s, without having to go through all the nag of clicking too much.

This has only been tested on Windows 10 in combination with Outlook 2013 and Outlook 2016.

$Key16 = "HKCU:\SOFTWARE\Microsoft\Office\16.0\Outlook\Profiles"
