@Bharat Suneja, "5. Thanks again for your feedback! As this post indicates, we are committed to and working hard on the next release of Exchange Server."
To me that sounds like MS has plugged tight its ears and doesn't hear the outcry of its worldwide admin base regarding the issues in Ex2013. Hence we cannot expect real focus on fixing the pain. Instead, what we get is yet another rushed product to meet your crazy timeline to release new software which probably will not bring anything new that would be of real use to anyone.
Here is another question for you, MS: what business need prompted you to create a new version of Exchange - I mean not YOU need to keep up with the new release pace at any cost, but REAL needs of your user base in the greater world (a.k.a. beyond the gates of Microsoft's headquarters)? What business or technical need isn't met by existing versions of Exchange? Do we REALLY need yet another new bag of bugs in 2-3 year's time?
