I’d highly recommend downloading and watching as while your clients may not be THERE yet as some point in time they will be.
I’m trying to lobby to get AzureADconnect officially supported on Essentials 2012 r2 and 2016. This is a “it works” but they think we’re going to try to run both the Office 365 wizard included in Essentials as well as Azure AD connect. This is a pick one or the other, you can’t do both. But given that Microsoft is leaning very strongly to where Azure AD connect is where they want us to go, it makes no sense that it’s not supported on Essentials which is (supposedly) their entry product into cloud services.
