Re: Dynamic device group from InTune user groups

This is exactly it. The tenant wants the configurations to be assigned to the device, not the user. 

I had to look up Autopilot - these are iOS devices, and hadn't encountered it. But it seems to be equivalent to Automated Device Enrollment. I didn't set this up (it was set up, just not by me), but researching has led me to Device Categories as a simple way of associating devices to departments, independent of users. Still wondering though, if a device doesn't have a user, will a dynamic group picking categories grab that device? Seemed like devices weren't available for grouping without a user.
