INTRODUCTION
Microsoft ActiveSync 4. does not support remote synchronization for Microsoft Windows Mobile-based devices. Because remote synchronization does not allow for strong authentication, we have determined that this feature is a security risk. Therefore, we have removed the remote synchronization feature from the following versions of ActiveSync:
 * ActiveSync 4.2
 * ActiveSync 4.1
 * ActiveSync 4.0



MORE INFORMATION
Earlier versions of ActiveSync enable remote synchronization for Windows Mobile-based devices. Therefore, you can perform remote synchronization. For example, in ActiveSync 3.7.1, the remote synchronization feature is available. Additionally, a synchronization option is enabled. The synchronization option that is enabled lets you synchronize a Windows Mobile-based device either by using a wireless network connection or by using a server. This is the default configuration.

In ActiveSync 3.8, the remote synchronization feature is available. However, all synchronization options for this feature are disabled in the default configuration. Therefore, you cannot perform remote synchronization.
