Chapter 3 Manually Configuring Devices 35
iPhone and iPod touch support Microsoft’s Autodiscovery service, which uses your user
name and password to determine the address of the front-end Exchange server. If the
server’s address can’t be determined, you’ll be asked to enter it.
After the Exchange account is successfully configured, the server’s passcode policies are
enforced. If the user’s current passcode doesn’t comply with the Exchange ActiveSync
policies, the user is prompted to change or set their passcode. The device won’t
communicate with the Exchange server until the user sets a compliant passcode.
Next, the device offers to immediately sync with the Exchange server. If you choose not
to sync at this time, you can turn on calendar and contact syncing later in Settings >
Mail, Contacts, and Calendars. By default, Exchange ActiveSync pushes new data to
your device as it arrives on the server. If you prefer to fetch new data on a schedule or
to only pull new data manually, use Settings > Fetch New Data to change the settings.
