Enhanced Certificate Enrollment and Management

Windows Mobile 6.5 includes a device-side enroller that is in ROM on all phones. In addition, an Exchange ActiveSync 4.5 desktop-side enroller enables the user to configure and initiate enrollment using a desktop user interface. Functionality includes creating certificate enrollment settings from Active Directory information, and the ability to use the desktop domain logon for device certificate enrollment.

Desktop Certificate Enroll enables the user to enroll a certificate to his or her device using desktop smart card authentication to the domain, without requiring a smart card reader or smart card software on the device. Enhanced security features available in Windows Mobile 6.5 support application-initiated enrollment, support deployments that require non-password authentication of the enrollment (smart card), and provide a way to renew expiring certificates.

These features:

  • Provide certificate-based authentication that can replace standard user name and password authentication
  • Enable flexible platform certificate enrollment that is configurable on the device
  • Allow applications to call into the certificate enrollment process programmatically to initiate enrollment
  • Support easy certificate renewal
  • Provide the ability to install additional certificates on the device without having to create a .CAB file

SharePoint and Windows File Share Document Access

SharePoint document access gives authenticated mobile users the ability to select links embedded in HTML e-mail to open documents stored on SharePoint servers. The same applies for Universal Naming Convention (UNC) shared documents. This can be used as an alternative to attaching files to e-mail messages, which is costly in terms of bandwidth and storage. This approach helps ensure that the recipient gets the most recent version of a document.

Mobile users are generally unable to access documents from outside a company firewall, but this problem is solved by using Microsoft Exchange Server 2010 as a proxy or redirector for the document. This approach allows HTML e-mail to contain links to SharePoint documents just like standard attachments.


Windows Mobile 6.5 provides read-only access to items stored in both SharePoint and UNC shares. These functions require Microsoft Exchange Server 2007 or newer. They are available on Windows® phones with Windows Mobile 6.0 and newer operating systems.

Exchange Search for E-mail

Exchange Search for e-mail enables Windows Mobile 6.5 users to search their Microsoft Exchange mailboxes for items that match specified criteria. The search results are downloaded and displayed in a search results folder. Having the ability to search e-mail in the user’s Exchange store is a powerful feature that helps users access critical information in their Exchange mailbox while away from a desktop.

The following features are supported:

  • Search for information in e-mail messages not stored on the phone
  • Search results appear in a standard messaging folder view
  • User can specify fields and folders to search, as well as date ranges
  • User can retrieve body content and attachments from search results
  • Results remain in the search folder until the next search, or until the user manually clears them
  • User can see the maximum number of search results available


These functions require Microsoft Exchange Server 2007 or newer. They are available on Windows® phones with Windows Mobile 6 and newer operating systems.

HTML Support in E-mail

HTML e-mail support for Microsoft Outlook Mobile® allows end users to receive, view, compose, and send e-mail in HTML format. The following messaging transports are supported: Exchange ActiveSync, POP, IMAP, and Exchange Server 2010. HTML functionality includes bullets, tables, hyperlinks, formatted text, and inline images.

HTML capabilities for Windows Mobile 6.5 software include:

  • E-mails synchronized with Exchange Server 2010 can display the original HTML formatting
  • HTML Smart Reply, Inline Smart Forward, Compose, and Fetch Mail are supported
  • Forwarded e-mail is not shown inline, as it is in desktop Outlook
  • E-mail preserves inline hyperlinks to Web content
  • Policy and user options: Control HTML payload per account via Configuration Service Provider and user options


These functions require Microsoft Exchange Server 2007 or newer. They are available on Windows® phones with Windows Mobile 6 and newer operating systems.

For a more detailed overview of Microsoft Exchange Server 2010 mailbox policies, see Understanding Exchange ActiveSync Mailbox Policies on the Microsoft TechNet Web site.

Distributed Server Roles

Two options are available for a Microsoft Exchange Server 2010 deployment, typical and custom.

In a typical installation, multiple service components (server roles) are added to a single server platform. A server role is a unit that logically groups the required features and components needed to perform a specific function in the messaging environment. The requirement of a server role is that it is a server that could be run as an atomic unit of scalability.

Server roles, the primary unit of deployment, enable administrators to easily choose which features are installed on an Exchange server. Logically grouping features in server roles offers the following advantages:

  • Reduces the attack surface on an Exchange server.
    • An administrator has the ability to add additional backend servers without disrupting Client Access Server operation or exposing these servers outside of the corporate LAN.
  • Offers simple installation, and the ability to fully customize a server to support your business goals and needs.
  • Potentially increases server performance by dispersing the overall workload (CPU and memory utilization) to additional server platforms.

The Microsoft Exchange Server 2010 server roles in a mobile messaging deployment are:

  • Client Access Server: This server hosts the client protocols, such as Post Office Protocol 3 (POP3), Internet Message Access Protocol 4 (IMAP4), Secure Hypertext Transfer Protocol (HTTPS), Outlook Anywhere, Availability service, and the Autodiscover service. The Client Access Server also hosts Web services and is required for all Active Directory sites that contain mailbox servers.
  • Mailbox Server: This server hosts mailboxes and public folders.


Additional server roles that are not mentioned or only briefly mentioned in this document include Edge Transport, Hub Transport, and Unified Messaging. The Client Access Server role is responsible for Exchange ActiveSync communication with a Windows® phone, and is the essential component of a mobile messaging deployment. See Network Architecture Scenarios and Exchange Server 2010.

For more information on Microsoft Exchange 2010 server roles, see “Server Role Documentation Roadmap” under Microsoft Exchange Server 2010 on the Microsoft TechNet Web site.

Exchange Management Console - Overview

In Microsoft Exchange Server 2010, the Exchange Management Console allows you to manage all servers, recipients, and organizational components in your IT infrastructure.

The Action pane lists the actions available to administrators, based on the items selected in the console tree or result pane. From a mobile messaging perspective, the Action pane is where a new mailbox policy may be created or a data wipe initiated for a phone.
