These sections provide information on how to configure real-time push notifications. With real-time push notifications, notifications appear on the device as soon as a new email arrives on the Exchange server.
Push notifications at specified intervals
You can also set up push notifications at specified intervals (interval-based) as opposed to real-time push notifications. With interval-based push notifications the notification interval is configurable by the administrator. For information on how to configure interval-based push notifications for Core deployments, see Cloud Notification Service for Email+ for iOS at https://community.mobileiron.com/docs/DOC-4443.
