Intune Device Lock Policy
The "Password" section of the Device Configuration Policy 'Windows 10 Device Policy' If the'password' is set to 'not configured' and 'Maximum minutes of inactivity until screen locks' set then the policy still applies.
In order to fix this I had to toggle Required for the Password Field then I could access the Field "Maximum minutes of inactivity" and set it to Not configured.
This seems like a bug. If the Policy is set to Not configured then it shouldn't configure anything but it was clearly configuring the maximum inactivity timeout still.

One year later and this is still an issue; my devices are locking after 5 minutes of inactivity despite having done what was described here (set to 30 minutes). Is there another setting like this elsewhere or is this the only one?
If so, setting the policy to "Not Configured" should *not* be implementing the lockout policy.
