Frequent synchronization can drain your battery, and synchronizing while roaming (using your device outside your home wireless service area) may incur additional charges for sending data. To reduce the cost and the drain on your battery, you can configure your device to synchronize more frequently during high-volume e-mail periods (peak times, such as working hours) and to synchronize less frequently during low volume e-mail times (off-peak times).
You can also use the peak times and off-peak times settings to schedule automatic synchronization between your device and a Microsoft Exchange Server every time that an item arrives in the Inbox or is changed.
Notes
ActiveSync on your device works with Windows Mobile Device Center (WMDC) on Windows Vista and with ActiveSync on Windows XP.
Step 1
Make sure that your device is not connected to your computer by a USB cable.
Step 2
Tap Start > Programs > ActiveSync.
Step 3
Tap Menu > Schedule.
Step 4
In the Peak times and Off-peak times fields, tap the down arrow to select your preferences. Because it can be expensive to synchronize while roaming, you may want to clear the Use above settings when roaming check box, and instead synchronize manually when roaming.
Step 5
Tap OK.
