Recently I performed a MS Exchange configuration review. For the "old" version of exchange we can use the Microsoft Exchange Best Practices Analyzer (link is dead) For the new version of MS Exchange (2013 and 2016) the tools must be download from the office 365 market (link is dead). But most of the MS Exchange server are not directly connected to internet. That is why I used a tool developed by Paul Cunningham: Exchange Analyzer available on github.
