There are a variety of mobile devices that can use Microsoft ActiveSync to synchronize with Microsoft Exchange Server 2007. You can manage the various devices that synchronize with Exchange Server 2007 by using ActiveSync mailbox policies. You can also manage ActiveSync properties for devices by using the Exchange Management Shell or the Exchange Management Console.

By default, if the Client Access server role is installed in an Exchange Server 2007 organization, ActiveSync is enabled for all users. A user can configure any device that supports ActiveSync to synchronize with the Exchange server. To simplify management of your ActiveSync devices, you can create ActiveSync mailbox policies. These policies can be applied to each ActiveSync user and can help you apply specific settings to a user's device. You can require that all devices accept the ActiveSync mailbox policy before they can synchronize with the Exchange server. Some of the available settings include the following:

• Require a password
  
• Require an alphanumeric password
  
• Allow attachments to be downloaded to the device
  
• Allow access to Microsoft Windows SharePoint Services documents
  
• Enable device encryption
