How about we narrate a story of Microsoft Exchange?
Microsoft is popular for its Operating System, Azure, AX, Office Products and certainly the power of Microsoft Exchange. Outlook is by far the best and most popular email client and it works very well with Microsoft Exchange.
The story is about migration of Microsoft Exchange. Our customer is a large enterprise with distributed offices, complex active directory setup and a vast volume of emails flowing in and out as I write. It is close to impossible for us to get a downtime ever, even if it is Christmas or the New Year. We got to find something else. Our customer had a need to upgrade from Microsoft Exchange Server 2010 to Microsoft Exchange Server 2013, its time to make the switch!
