We are a mixed environment ME5 and ME3. Testing out Windows Defender ATP and onboarded our first device with no issues. The question is with a mixed license environment can we onboard all devices just because we have an ME5 even though a ME3 user might use it? So in a 200 E5 and 500 E3 environment only 200 out of the 700 devices have ATP activated? Been reading for hours now and there is no clarification on how it is activated and reports if you onboard all devices.
