You can manage Microsoft ActiveSync properties for users by using the Exchange Management Shell or the Exchange Management Console.

By default, if the Client Access Server role is installed in a Microsoft Exchange organization that is running Exchange Server 2007, ActiveSync is enabled for all users. You can disable ActiveSync for a user or group of users and also manage various settings for your ActiveSync users.

To simplify management of your ActiveSync users, you can create ActiveSync mailbox policies. These policies help you apply specific settings to a single user or group of users. 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.
