When starting ActiveSync for the first time, you are prompted to create a synchronization relationship with your mobile device. When you set up a synchronization relationship, you select synchronization and file conversion settings, which are contained in a file on your PC. This file enables your PC to recognize your device. Only devices that have a synchronization relationship with a PC can synchronize information with that PC.

Your PC can set up synchronization relationships with many different devices, but a device can have synchronization relationships with at most two PCs. For example, you can keep the same contact information on your PC at work, your PC at home, and your device. No matter where you are viewing information, you will have the information you want at your fingertips. However, you can synchronize e-mail messages between your device and one PC only.

Note   If the two computers with which you want to set up synchronization relationships are both connected to Microsoft Exchange, you can set up a synchronization relationship with only one.
