Microsoft today announced that Sony Ericsson has licensed the Exchange ActiveSync protocol to enable wireless synchronisation between Exchange Server 2003 and Sony Ericsson's forthcoming P990 and M600 smartphones.

The application is designed to provide mobile workers with wireless access to their complete Exchange Server 2003 information, including email, calendar and contacts.

Microsoft added that, for organisations with Exchange Server 2003 Service Pack 2, additional mobile services such as Direct Push are also supported, providing instant access to newly received email.

Both Sony Ericsson phones will be available in the second quarter of 2006.

"Organisations today require a secure wireless solution for their mobile workers that is easy to manage and supported by a variety of devices," said Jeff Ressler, director of product management and planning for Exchange Server at Microsoft.

Current Exchange ActiveSync licensees include DataViz, Motorola, Nokia, Palm and Symbian.
