Bharat,
Any update on a fix yet? When I go to the toolbox and launch the Best Practice Analyzer for Exchange 2010, it seems to only send me to the Exchange 2013 versions of the articles now. I don't even see an option to select the Exchange 2010 version of the article. That makes little sense. First, because I'm not running Exchange 2013 - and can't even consider it until SP3 is released. Second, the vast majority of Exchange systems are on 2003, 2007, and 2010. I'll bet less than a few percentage points of companies are currently on Exchange 2013 - so why update the content that breaks links for 95%+ of the administrators of these systems?
It's like you have gotten your priorities backwards. You shouldn't be trying to shove Exchange 2013 down our throats yet. Instead, you should be continuing to help support us on our CURRENT deployments of previous versions of Exchange. What's going on in Redmond? Are you smoking the wacky tobaccy or something? Would you change things back asap.
