I have Windows 10 build 1607 clients and have updated the ADMX files to the latest ones.
Is there any way to control/lockdown the native Windows 10 mail app using Group Policy? The only option I can find in GP currently is enable/disable. At the very least I want to stop users from adding email accounts to it. Also ideally I'd like to deploy settings for our Exchange mail system to the app, so that the users can access their exchange mailbox from outside of our network.
