Exchange Server 2003 service pack 2 is expected to be available at the end of the year. One of the major feature changes will be mailbox stores of up to 75 GB for Exchange server standard and SBS2003. The mobile messaging area will see a number of improvements, including the ability to send a remote wipe command to lost devices, to prevent someone from accessing data stored on the device.
