CRM 2015 launch not following Default_Client_Config.xml

I'm trying to automate a rollout of CRM 2015. I have it set so that the installer places the Default_Client_Config.xml file with the below info into C:\Program Files (x86)\Microsoft Dynamics CRM\. The problem is, when we go to open Outlook, it's not auto-adding the organization. The user is prompted for the organization URL instead of their credentials for configuring. What am I missing?
