SP1 will be continuing to expand the scope of the Exchange Web Services API introduced in Exchange 2007. This API enables you to create applications that take advantage of the flexibility and functionality of Web services technology.
New in this release is the inclusion of ConvertIDs in Exchange Web Services.
This will make it easier for environments that use both OWA and Outlook clients, so now folders and items retrieved from Web Services can easily be referenced in OWA.
