Powershell Office365 Employee Photo Upload Script

Hello,

I wrote a script for a resource group to use, but I think I'm doing something wrong... The script crashes Powershell when I try to exit the script from within the script... I've tried changing my "exit code" around a bit, and I have gotten "[environment]::Exit(0)" to work without crashing, except it will close the Powershell window I'm working on, and plus, I think there should be a more "elegant" way of doing this... But I haven't Powershell'ed in a while, so I'm not as "fresh" as I should be.
