Remove Spam Email from everyone's mailbox - Powershell

A gui based script that allows you to search for an email subject line on all user mailboxes, show the result count, and allow removal with a single click. Script defaults to emails from the last 2 days. This script is not responsive so it will act like its frozen until results are found. Run in powershell ISE for best results.
