I want to share this interesting note to Microsoft's vice president:
Over the past several weeks, I've had the opportunity to present interviews with members of the Microsoft Exchange Server team, talking about topics such as the Personal Archives feature of Exchange Server 2010, improvements to unified messaging (UM) and Exchange Online, and the importance of the Exchange ActiveSync protocol. To round out this series, I spoke with Microsoft corporate vice president Rajesh Jha about what the future holds for Exchange Server. Of course, much of this conversation focused on the role Exchange plays in Office 365 and the cloud, but Rajesh also had a lot to say about the importance of listening and responding to the requirements of customers and embracing changes in technology as a way to move the Exchange team forward.
