ActiveSync is a data synchronization program developed by Microsoft for use with its Microsoft Windows line of operating systems. It is the latest sync software release for Windows Mobile-based devices. ActiveSync provides a great synchronization experience with Windows-based PCs and Microsoft Outlook right out of the box.

ActiveSync acts as the gateway between your Windows-based PC and Windows Mobile-based device, enabling the transfer of Outlook information, Office documents, pictures, music, videos and applications to and from your device.

In addition to synchronizing with a desktop PC, ActiveSync can synchronize directly with Microsoft Exchange Server 2003 so that you can keep your e-mail, calendar data, tasks and contact information updated wirelessly when youre away from your PC. ActiveSync 4.5 supports PC sync via USB cable, Bluetooth, or infrared connection.

You can synchronize information automatically as items arrive only if your company is running Microsoft Exchange Server with Exchange ActiveSync.

How to change the synchronization schedule
Using ActiveSync, you can schedule synchronization of your device on two separate schedules. Use the peak times schedule to synchronize during working hours or other times you experience higher mail volumes. Use the off-peak schedule to synchronize during times when you experience lower mail volumes. When you are roaming, you can synchronize manually to reduce roaming charges, or you can synchronize using the mobile schedules.
1. In ActiveSync on the device, tap Tools > Options > Mobile Schedule tab.
2. To synchronize periodically during peak times, select the frequency of synchronization in the Peak times list.
3. To synchronize periodically during off-peak times, select the frequency of synchronization in the Off-peak times list.
4. To synchronize while roaming, select a frequency in the Roaming list.

Tip: The power-off timer is reset each time the device synchronizes. If you set a synchronization schedule that is more frequent than the time set for the device to automatically power off, the device will never turn off to save battery power.
To set the days and hours for peak times, tap Peak Times.

How to synchronize automatically
With ActiveSync you can schedule automatic synchronization between your device and a server every time an item arrives or is changed at the server. Your device is informed of that event and synchronizes automatically to retrieve those items, making your device always up-to-date.
1. In ActiveSync on the device, tap Tools > Options > Mobile Schedule tab.
2. Do one or both of the following:
To synchronize as items arrive during peak times, select As items arrive in Peak times.
To synchronize as items arrive during off-peak times, select As items arrive in Off-peak times.
3. When finished, tap the Server tab.
4. Tap Options.
5. Tap Device Address.
6. Do one of the following:
In Text messaging address for this device, enter the address that identifies your device on the network. This is the same address that other Internet users use to send text messages to your device.
If your company has instructed you to use a pre-defined service provider profile, select the profile name in the Service Provider list, and enter your device phone number, if necessary, in Phone number for this device. If you do not want to use the provider profile, select Other in the Service Provider list. Then enter the address that identifies your device on the network in Text messaging address for this device.
