Android MAM App configuration blocks MDM app settings

Hi everyone, 

I am running into a problem with Android Outlook app configuration. 

I set an app config profile for Outlook to block contact sync for managed apps and a BYOD MAM scenario. The profile can't be set for specific device types. I just want to apply on unmanaged devices. 

The Problem is, users with a managed device who also want to use managed apps on their personal device get the same Outlook config profile on both devices, what results in managed devices unable to sync contacts to the native contact app. 

Apart from using only one device type, do you have any ideas how to solve this issue? 

Thanks, Simon
