Send Feedback

The Messaging and Security Feature Pack for Windows Mobile 5.0 enables OEMs and Operators to provide a direct push solution to Windows Mobile 5.0-based devices. The Messaging and Security Feature Pack (MSFP) works with Microsoft Exchange Server 2003 SP2.

MSFP is a software upgrade that provides a mobile messaging solution that uses the management benefits of Exchange ActiveSync, which is a part of Exchange Server 2003, and new security policies on the Windows Mobile 5.0-based devices. Exchange Active Sync is an Exchange synchronization protocol that is designed for keeping the Exchange mailbox synchronized with a Windows Mobile 5.0-based device.

MSFP helps Enterprise administrators to better manage devices, and helps businesses improve mobile device security. It also allows the mobile information workers to stay connected to their Microsoft Outlook e-mail, corporate contacts, calendar, and task information.

The following table shows how MSFP benefits businesses.

Password enforcement

Helps prevent unauthorized access to a device by automatically removing device data when the password is entered incorrectly a specified number of times.

Certificate-based authentication

Increases security for accessing Microsoft Exchange Server 2003 Service Pack 2 and eliminates the need to store corporate log-in credentials on the device.

Native S/MIME support

Helps protect e-mail content with native support of Secure/Multipurpose Internet Mail Extension (S/MIME) for signing and encrypting messages with digital certificates.

For more information, see Device Protection with MSFP.

Cost-effective mobile messaging solution MSFP helps keep mobile messaging costs low because it allows the use of existing Exchange Server 2003 SP2 investments, which reduces the need for additional third party server product and client access license fees.
Messaging support
Enables companies to use their existing Microsoft Exchange Server 2003 investment; eliminates the need for additional non-Exchange third-party server products and client access license fees.
GZIP data compression
Reduces Mobile Operator network use by compressing data, thereby optimizing data bandwidth.


The following lists shows the MSFP requirements:

  • Upgrade from Exchange Server 2003 to Exchange Server 2003 SP2.
  • Direct synchronization with the Exchange Server. PC synchronization is needed only for Certificate-based Authentication, which requires a one-time connection to ActiveSync for certificate deployment and periodic connection at certificate renewal time.
  • Users having some type of data connection (GPRS or desktop pass-through using ActiveSync 4.1) in order to use the GAL functionality.
