Unmanaged Devices setting - allow full acces to only some SharePoint sites and restrict access on new sites
Currently in the Unmanaged devices setting in the SharePoint Admin portal you can allow full access, limited access or no access to all sites from unmanaged devices.
If you wish to give full access to just a few of your site collections and restrict access on all the rest you need to allow full access, then use PowerShell to restrict access on all sites and use PowerShell again to allow full access to a particular site collection.
The problem is everytime a new site collection is created you need to run PowerShell again on each new site to restrict it. When site collections are created regularly in your organisation this is not manageable. It would be ideal to have the ability to automatically restrict all newly created sites so that only the ones specified to have full access have this setting applied.
