#Created by: Taylour Blackwell and Brian Zoucha
# Filename: O365MailFlow_v6.ps1
# Based on: DIY O365 Monitoring by Rob Rinear
# Description: This will simulate a user sending an email from one O365 account to another O365 accou and then verify that the email was received.
# O365 --> O365
# Updates: V2- Updated 7/11/17- removed old unneeded code, Updated the log entries to include identification of sender and reciever accounts
# V3- Updated script to use variable for EWS URL
# V3.5- Updated 7/28/17- Turned the sleep integer into a variable so that it can be modified as an overidable parameter
# V4- Updated 8/2/17- Added sender and Receiver accounts to property bag.
# V5- Updated 9/19/17-TB- Adding stopwatch to allow for timing duration of scripts
# v5.5- Updated 1/29/18-IA- Ismaen Aboubakare added error checking to the script.
# TB- added comments and added the error checking to the property bag.
# Updated 8/15/18-TB-Fixed issue with total time not adding correctly
# v6- Updated 10/31/18 -TB- Added integer for stopwatch to add to the property bag for the performance rule
