Exchange 2016 iApp RC2 issue

There doesn't appear to be a response when run from an ssh session and substituting the various data for our servername, email, and user account.

Its possible I am executing it wrong I suppose. I have removed any sensitive information from the version I ran. We have logged into the mailbox and sent a message so there would be content in the folder to ensure its working properly.
