Some people drink so much Microsoft Kool-Aide and cannot possibly fathom ever using anything else but Microsoft software. Every possible problem looks like a Microsoft solution. If the solution isn't obvious, call the Microsoft Rep and find one! Then the predictable "what are you going to do, roll your own?!" remark... failing to realize there's more than just one SaaS company in the world. How do you wager all the big businesses around the world accomplish all of these things you mentioned? What about all the big businesses in Russia, China, India and more? Hint - they're not all using Microsoft products and Azure... Do you believe Microsoft is the only SaaS offering inboxes, storage, automation and more? Do you believe nothing else can use open protocols such as LDAP? Microsoft's moat is deep, but it's not necessary. Most people eventually figure this out for themselves.
