Microsoft Corp. today announced that Sony Ericsson has licensed the Exchange ActiveSync® protocol to enable more secure, wireless direct synchronization between Microsoft® Exchange Server 2003 and Sony Ericsson’s P990 and M600 phones. This solution will help provide mobile workers with anywhere access to their complete Exchange Server 2003 information, including e-mail, calendar and contacts. For organizations that have deployed Exchange Server 2003 Service Pack 2, additional mobile enhancements such as Direct Push are also supported, providing instant access to newly received e-mail messages. Both of the new phones will be available in the second quarter of 2006.

Microsoft is experiencing significant momentum with Exchange Server with a five-year compound annual growth rate of more than 20 percent. According to analyst firm Gartner Dataquest, Microsoft Exchange is the 2004 market share leader in enterprise e-mail and calendaring software, based on new license revenue, with a share of 48 percent (“Market Share: Enterprise E-Mail and Calendaring, Worldwide, 2002–2004,” Gartner Dataquest, June 2005). By licensing Exchange ActiveSync, Sony Ericsson is now able to deliver a comprehensive mobile messaging solution to these customers.
