No, Exchange is not all that helpful unless you want all the bells and whistles. I don't blame you at all. It doesn't come with Essentials anyway. Just so you know in case you do decide to go with Standard, like most things, if the OS is installed correctly, you won't even know it is there. There is no maintenance.
But, like I said, it's not in Essentials. For Word, Excel, PowerPoint and Outlook; you have to subscribe. That could be rather cool. Haven't tried it yet. Thanks for the explanation.
