Sorry to revive this old thread but it's exactly the same thing I was trying to find out.
Is the hard reset mechanism (by that I mean pressing volume and power keys and then getting to the Android Recovery Mode) also blocked by Workspace One in any way? And if it's not, is the user prompted back for WS1 enrolling the moment the devices reboots during the Android setup screen?
On our rugged Android Honeywell devices, this feature is not blocked. However, the device is then stuck in Factory Reset Protection, so while the device is no longer working for us, it no longer works for them either.
Thanks Matthew for your reply. Yes, in case FRP is enabled, that would only cause one extra headache (though as administrator you can always use the Enterprise Factory Reset Protection as a workaround for that if I'm not mistaken).
But if FRP is not enabled, I don't know which would be the final scenario (that's if FRP can be disabled while enrolled to WS1).
We use the method you describe to rescue such devices.
I've never tried disabling FRP (is it possible?), but I'm pretty sure it would let the person go on their merry way with a reset in the scenario you describe. If I recall correctly, there may have been some device which truly disabled factory resets through the device boot menu, but I don't believe that is the case for all vendors.
