The iOS 10.3 release started rolling out on March 27, 2017 to iOS users. All existing Intune MDM and MAM scenarios are compatible with the latest version of Apple’s OS. We anticipate all existing Intune features currently available for managing iOS devices will continue to work as your users upgrade their devices and apps to iOS 10.3.
There are currently no known issues to share. If you run into any issues with iOS 10.3, please feel free to reach out to the Intune support team through the local numbers listed here. We will continue to update this post (as needed) as we release additional information and hear from you.
