Users with Multiple Devices - Groups Best Practice

Hi StuartK73 , 

I had the same scenario for one of our customers, in that case, what I would suggest,

Just create a Dynamic Groups.

Example:

Windows 10 laptop 

• (device.deviceOSVersion -startsWith "10.0") and (device.deviceOwnership -eq "Company")
• (device.deviceOSVersion -startsWith "10.0") and (device.deviceOwnership -eq "Personal")

iOS Personal phone

• (device.deviceOwnership-eq "Personal") 

iOS DEP / Corp phone 

• (device.enrollmentProfileName -eq "DEP iPhones") 

Android Enterprise Work Profile 

• (device.deviceOSType -contains "AndroidEnterprise")
• (device.deviceOSType -eq "AndroidForWork")

MacOS

• (device.deviceModel -eq "iPad Air")

And then simply create your Intune Management Profiles and Categories based on those created groups. 

And don't forget to benefit of using device categories.
