  <p>Not quite enough information or exactly what we need. Here is the scenario. Customer is NOT on Office 365. They are only on Office 2016 on-prem. They want to create an Office.JS add-in for Excel and Word and have it mandatory load for all users. </p>
  
  <p>How do we sideload a mandatory add-in across the enterprise? What are the registry keys or other information we need to provide so that Word and Excel will find and load the manifest to the project for all users?</p>
