Hello,
we use around 500 Devices in our company that arent assigned to a specific Employee (They are shared by teams) but could benefit from having access to our Contacts from the Exchange Server, the devices are locked down with secure launcher. (XCover 4, Android Enterprise Enrollment) Since they arent personalized, a mail profile isnt a good solution, id like to just sync contacts to the devices, without giving them access to any kind of mail account.
