1.    On the phone Home screen, click Start > ActiveSync > Menu > Schedule.

2.    Do one or both of the following:

       Under Peak times, select As items arrive. It's more cost-efficient to synchronize on at

       regular intervals when mail volume is high.

       Under Off-peak times, select As items arrive. This can be more cost-efficient than

       synchronizing on a regular schedule when mail volume is low.

3.    When finished, click Menu > Device Address to provide Exchange Server with the address to

       use to contact your phone.

4.    Click Done.
