Hello Kunal, The classification into groups is independent of the OS. As long as the device is registered in MobileIron, it is classified into the corresponding group based on its attributes in MobileIron's DB. Can you check in MobileIron if the windows mobile devices have an ownership attribute like apple devices? Another a bit more cumbersume option is to configure netsight mobileIron's module for a Debug log (https://:8443/fusion_jboss), find a windows mobile device in the log at /usr/local/Extreme_Networks/NetSight/appdata/logs/server.log and check the logged attributes. After this process, restore the log level to its original value to avoid filling the disk with logs.
