Can auto-update of contacts via Exchange GAL be disabled?
I've found that the iOS 8.4 automatically updates a user's contacts with info from an Exchange Global Address List. I didn't expect this to be the case, but having run some tests on two iPhone 6 users shows that it's happening.
Unfortunately, one of the users wants to modify the contacts for various company employees, but after a day or two those changes get reverted when Exchange ActiveSync overwrites them from the GAL.
Is there a way to disable contact updating from the GAL?
