Exchange 2010

As more and more companies are adopting BYOD supporting a broad set of end user devices security and device management take on greater importance. As we are left wonder where the BlackBerry Enterprise Server will fit into the current and future state of enterprise messaging other vendors and technologies are left to fill the gaps. Anyone who has been working with Exchange for some time knows that ActiveSync has been around for a while; its recent evolution brings us to the current version which is part of Exchange 2010.

With BYOD security has taken on a greater importance and with that Exchange 2010 provides a number of features to address this, from both the server perspective and the device perspective. There are still a number of things that need to be addressed but Microsoft is moving in the right direction.

Mobile Device Management in Exchange 2010 has come a long way from its beginnings. I would expect in the next Exchange release to see an even greater feature set including additional reporting and analytics.  Until then there are a number of great resources out there that can help with ActiveSync policy management, protocol management and device information.
