Use HoloLens offline

HoloLens support a limited set of offline experiences for connectivity conscious customers and for customers who have environmental limits on connectivity.

Near-offline setup

HoloLens need a network connection to go through initial device set up. If your corporate network has network restrictions, the following URLs will need to be available:

HoloLens limitations

After your HoloLens is set up, you can use it without a Wi-Fi connection, but apps that use Internet connections will have limited capabilities when you use HoloLens offline.
