Exchange ActiveSync in Exchange 2007 SP1 has several enhancements for administrators and performance enhancements for end users. These enhancements include a default Exchange ActiveSync mailbox policy, improved policy settings, and remote wipe confirmation. There are also enhancements to the Direct Push protocol to reduce how much data is exchanged between the device and the server.

• Exchange ActiveSync default policy   When the Client Access server role is installed on a computer that is running Exchange 2007 SP1, a default Exchange ActiveSync policy is created. Users who do not have a current Exchange ActiveSync policy will implicitly inherit this new default policy. You can modify the default policy to change the settings for all users or create new policies for a subset of users. You no longer have to perform the extra step of assigning new users to a policy. You can also designate any existing Exchange ActiveSync policy as the default policy.
  
  
• Additional Exchange ActiveSync policy settings   There are many new Exchange ActiveSync policy settings in Exchange 2007 SP1. Some of these settings include the following:
  
  
  • Disable Removable Storage
    
    
  • Disable Camera
    
    
  • Disable Wi-Fi
    
    
  • Disable POP/IMAP e-mail
    
    
  • Block Internet Sharing
    
    
• Remote Wipe Confirmation   Exchange 2007 lets an administrator issue a remote wipe command through the Exchange Management Console or the Exchange Management Shell. The user can also issue a remote wipe command from Outlook Web Access. This command will clear all user data from the mobile device and can be used if the device is lost or stolen. It is also a helpful way to clear data from a device when a device is reassigned to a new user. In Exchange 2007 SP1, the originator of the request receives a confirmation message when the device acknowledges the remote wipe request. If the user originates the request through Outlook Web Access, they will receive a confirmation e-mail. If the administrator originates the request, both the administrator and the user will receive a confirmation e-mail.
  
  
• Direct Push performance enhancements   Direct Push operates by establishing a long-standing HTTPS connection between the device and the Exchange 2007 server. In Exchange 2007 SP1, the size of the HTTPS request and response headers has been reduced. This reduces how much data is sent and received from a mobile device.

Outlook Web Access is an ideal client for users who do not have access to Outlook, such as users who are traveling or who rely on shared workstations for access to e-mail and calendar information. Outlook Web Access was completely rewritten for Exchange 2007. This provided an opportunity to add many new features, but not all the features from earlier versions of Outlook Web Access were incorporated into the new version. With Exchange 2007 SP1, those missing features have been returned and new features added.

Changes to Outlook Web Access Light   Outlook Web Access Light is a less complex version of Outlook Web Access that is designed to work with nearly all Web browsers. In Exchange 2007 SP1, Outlook Web Access Light has been improved by adding monitoring of the composition forms as follows:

• Activity is monitored while a user is composing a long entry of any type (such as a message or calendar entry) so that the session does not time out while the user is still typing.
  
  
• If the entry is a message, the message is automatically saved in the Drafts folder if the session times out because of inactivity while the message compose form is open.
  
  

Changes to Outlook Web Access Premium   Outlook Web Access Premium works with Internet Explorer 6 or later versions and has a richer user interface than Outlook Web Access Light. The following features have been added to Outlook Web Access Premium in SP1:

• Users can create and edit Personal Distribution Lists.
  
  
• Users can create and edit server side rules.
  
  
• WebReady Document Viewing, a feature that translates an attached document into HTML so that it can be viewed as a Web page, has added extra support for the following Microsoft Office 2007 file formats:
  
  
  • Word documents: .docx
    
    
  • Excel worksheets: .xslx
    
    
  • PowerPoint presentations: .pptx
    
    
• In Exchange 2007 SP1, users can access the dumpster from Outlook Web Access and can use the Recover Deleted Items feature.
  
  
• Outlook Web Access has a monthly calendar view in addition to the daily and weekly views.
  
  
• Move and copy commands have been added to the Outlook Web Access user interface. Users can move or copy folders by using a command in the right-click menu of the folder list. Users can also move or copy individual items in message folders and public folders by right-clicking inside the item list or by clicking an icon on the toolbar.
  
  
• Public Folders is back and offers the following features:
  
  
  • Full access to public folders from Outlook Web Access without having to use the /public virtual directory
    
    
  • Full access to public folders on Exchange 2007 Mailbox servers without having to keep an Exchange 2003 Mailbox server available for Public Folder access from Outlook Web Access
    
    
  • Public Folder search capabilities
    
    
  • Support for Web Parts
    
    
• S/MIME in Exchange 2007 SP1 supports the following:
  
  
  • Reading signed and encrypted e-mail
    
    
  • Composing signed and encrypted e-mail
    
    
  • Using the Options page to configure settings for the S/MIME control after it is installed or reinstalled
    
    
  • CNG support and Suite-B compliance
    
    

Note:
S/MIME requires Internet Explorer 7.

• Additional customization features that include the following:
  
  
  • The ability to integrate with custom message types in the Exchange store so that they are displayed correctly in Outlook Web Access
    
    
  • The ability to customize the Outlook Web Access user interface to seamlessly integrate custom applications together with Outlook Web Access. For more information see Customizing Outlook Web Access.
