On 6 June 2005, Microsoft announced its Messaging and Security Feature Pack for Windows Mobile 5.0. This is a series of enhancements for e-mail servers running Exchange 2003 with Service Pack 2 and clients running Windows Mobile 5.0. Features include "push" technology for e-mails and remote management of devices.
Gartner believes this pack, and earlier deals to license Microsoft's Exchange Server ActiveSync protocol, will make the company's mobile e-mail offering a "good enough" solution for some organizations. Security remains a problem, and enterprises should use third-party security products if they choose to deploy Microsoft's e-mail solution (see "Security in Windows Mobile 5.0 Messaging Pack Disappoints" ).
The messaging enhancements make Microsoft's offering a viable alternative to more-expensive gateway-based solutions from providers such as Research in Motion. Because it doesn't need an additional gateway, it will appeal to companies that already have Exchange servers and, due to limited budgets for mobile e-mail, are keen to control costs. Firms that have Exchange servers but have chosen to deploy gateway-based mobile e-mail for a few users will be able to use the new offering as a quick way to give mobile e-mail to many more employees.
Microsoft's product still lacks some features compared with dedicated mobile e-mail solutions. The pack adds what Microsoft calls Direct Push Technology, but this seems to be less efficient than other push implementations. It relies on devices maintaining a Secure Sockets Layer connection to an Exchange server by sending small packets of data. Microsoft's e-mail solution does away with the need for a network operations center to route e-mail to mobile devices. Enterprises with stringent security requirements may perceive this aspect as being less secure.
