Apple recently released a new iOS version for use on iPads and iPhones, iOS 11. You may experience difficulty connecting to Middlebury College email hosted by Microsoft when using the native iOS Mail and Calendar Apps. ITS recommends you use Outlook for iOS available free in the App Store. Apple and Microsoft are working on a solution. UPDATE: this issue was resolved with iOS 11.0.1.
Apple also announced the next version of macOS, High Sierra, available 9/25/17. ITS has instituted a block on the installation of this OS on college managed computers until it can be tested with college systems and software. Our High Sierra webpage (http://go.middlebury.edu/highsierra) will provide updates as they become available, including notes about any known issues and resolutions.
