Configure Exchange ActiveSync on iOS Devices

Configuring Exchange ActiveSync on iOS devices provides secure access and storage for your email and attachments. It syncs emails, attachments, contacts, calendars, and other accounts between the devices and the Exchange server, thus providing access to this information even in the absence of a network connection. Exchange ActiveSync provides standard encryption services like SSL encryption to add security for mobile communication with the server. Hexnode allows the admin to configure ActiveSync settings for iPhone and iPad via the MDM console.

Note:


This functionality is available on Pro, Enterprise, Ultimate and Ultra subscription plans.
