Most Enterprises we talk to about moving to the cloud consider more only Microsoft Online Services, which is fine of course. We at Wortell focus on the Microsoft stack, but really feel there should be some competition out there because it's good for the market.

Sometimes however companies choose Google Apps, which, to be honest, I don't really understand. Don't get me wrong, Google Apps is a great product if you want to do consumer E-mail. Compare both Hotmail and Google Apps and you'll find there somewhere on the same track.

Microsoft just published a new case study which clearly states the case. Eric Rees, director of a 2000 people large company states the following:
