RollOut: Microsoft Exchange 2007 Beta 2: Page 4 of 6

Outlook Web Access also adds a new layer of protection for mobile device users, who can wipe data off smartphones and PDAs remotely. The user logs in, then opts to have a device implode upon the next synchronization. This is handy for erasing data from a lost or stolen PDA. Obviously, it will only work if the PDA is turned on and has access to an Internet connection. Furthermore, there's no mechanism for preventing users from accidentally erasing all their data. Fortunately, the wipe command doesn't erase the user's actual mailbox.

Unified Messaging 1.0

Microsoft has been a big supporter of SIP (Session Initiation Protocol), and it has pulled several unified messaging features into Exchange 2007. Some of these are available in competing unified messaging products from Alcatel, Nortel and Siemens. Exchange Server 2007 is designed to deliver voicemail, faxes and e-mail to users' inboxes and lets users access those messages by phone or the Web.

We didn't have a PBX set up to test the UM features, but will do so when the final version ships. An on-site demo highlighted a speech-recognition program that lets a user have his calendar read to him, then respond with messages such as "I'll be late." Although voicemail is supported, you can't compose e-mail messages by speech.
