If so go here: http://exchange.ideascale.com/ and you can post your idea or vote on it if someone else already has one similar.
Tony Redmond blogged about this site also here: http://thoughtsofanidlemind.com/2013/12/09/exchange-improvements-site/. He is planning on having a Q&A session with Perry Clarke, Microsoft CVP for Exchange, on 12/13. For more on that see Tony’s post here: http://windowsitpro.com/blog/what-question-would-you-ask-microsofts-exchange-development-supremo
So we, the Exchange MVPs & others, have started to populate this idea list and could use your help on voting (up or down) and posting new ideas. We hope this site will be come a great place for sharing and voting on ideas and that the Microsoft Exchange team will start to look at it for ideas on what to do or fix in future releases.
