What I'm saying is, you get a huge amount of feedback and known bugs from this blog, and they stay unfixed for months. Yes you need to work a lot better with the community, but production users were used as beta testers anyway for Exchange 2013 and its
released updates, and their feedback for the bugs was basically ignored. We submitted bugs and reports from an attempted 2013 install, and the reply from Microsoft was (exact quote) 'I’m very sorry that you’ve had difficulties installing Exchange 2013 into
your Exchange 2010 organization. " and that the product team would get back to us. After a month trying to follow this up we gave up, nobody at Microsoft cared. And yes, we're a Microsoft Partner.
