As much as open source guys like myself love to bash on MS, there is just something they do right. And if its not right, sometimes they are just the only guys in town. And one of those things in Microsoft Exchange. No one has yet been able to replicate the full experience of Outlook + Exchange in terms of calendaring and E-Mail, especially if your looking for a non-cloud solution. Hell even many Web 2.0 companies who are ready to accept non-Microsoft products have a hard time walking away from Exchange. But in that case you might run in to a case you might have a Exchange Server but a Client using Linux, and that is what I ran in to helping LinkedIn move to Exchange 2010. So what are you to do? Well we got a fix for you.
