User's Manual

If you have a PC which is already fully synchronized with your
Exchange Server, then synchronize your device to your PC the very first
time instead of synchronizing through to the Exchange Server. This will
allow faster synchronization.
To synchronize direct through to your Exchange Server instead of your PC,
click the box above and enter the Exchange Server details as shown below .
Ensure that your PC has a connection which is accessible to the Server as
the setup will check the connection and that your User name / Password
settings above are valid also.
