In this webcast, Harold Wong, IT Pro Evangelist, Microsoft Corporation explores Microsoft Exchange Server 2007 Client Access Services. The overall goal of Client Access Services is to add value to the data in your inbox by enabling you to access that data from wherever you are. In addition to access from Microsoft Office Outlook 2007, Microsoft Office Outlook Web Access (OWA), and mobile devices, we cover some new client access features introduced in Exchange Server 2007. We look at the various underlying components of Exchange Server 2007 Client Access Services and we describe improvements to calendaring functionality, the new Unified Messaging, Exchange Web Services, and programmatic access to messaging data. We conclude this webcast with a look at enhancements to Exchange Server ActiveSync.
