You have over 500 enrolled Android and iOS devices and need policies targeted by OS version. What should you configure first so devices can be targeted by their Android or iOS version?

To target policies by OS version for a large number of devices, dynamic Azure AD groups are the most efficient solution. You can create dynamic groups with rules based on device properties like device.operatingSystemVersion. This automatically adds or removes devices from the group as their OS versions change, ensuring policies are always applied to the correct devices without manual intervention. Device categories in Intune are used for grouping devices for administrative purposes, often based on department or function, not OS version. Corporate device identifiers are used to identify and manage corporate-owned devices, primarily for enrollment restrictions or identifying specific devices, not for dynamic targeting by OS version. Device settings in Azure AD refer to general device configurations, not a mechanism for creating dynamic groups based on OS version for policy targeting.
