Hot on the heels of their 'Black Knight' article, Forbes has published an update story following Gartner's recent findings that Exchange is now the undisputed leader of the messaging server market. I've known this for a long time because I can see exactly how many licences Microsoft has sold, but it takes analyst firms longer to refresh their data and report on key market trends. Even though this is old news, it's still great news for Exchange Server which continues to go from strength to strength. In fact, we've got so much interest from organisations wishing to move away from competitor products right now that we're having to lay on new training events to meet demand. A nice problem to have.
