Recently our Android users are reporting that they are unable to toggle "sync contacts" in Outlook mobile. The option appears on initial setup, but after "Device Administrator" turns on, the option is no longer listed. The same for sync calendar.
Toggling the option for users to change the setting has no impact. Users don't see it. So, my option is only to force all users to sync contacts, or none. The same goes for calendar.
If I attempt a managed device profile just to auto configure mail, but try and use the managed apps profile to configure sync options, there is no change. If I remove the managed apps profile for Outlook on the device, re-enroll the device, then contact and calendar sync work. Though, you will still be unable to toggle the setting as a user.
