prefer to fetch new data on a schedule or to only pull new data manually, go
to Settings > Fetch New Data to change the settings.

Please note that not all Exchange features are supported (for example, folder management). Additionally, by default, the communication between the iOS device and Exchange Server is secure, using 128-bit SSL encryption and X.509 certificates.
