Script Issue - Process[0]?

Good Morning Everyone,

I have written a script to get a list of users from Active Directory and compare them with mailboxes we have in O365 to get their ForwardingSMTPAddress - for some reason I am getting prompted to enter: Process[0] when my For-Each loop starts, I am unsure of where the error is in my script, please could you take a look and advise. Thanks
