In the race of Exchange 2016 support, all control panels would be trying to reach the finishing point earlier. I see on a website panel forum post that they would be soon implementing it in January 2016.
 
What is the roadmap of Hosting Controller for providing Exchange 2016 automation?

Yes, its much awaited for Exchange 2016. I have seen in one of the announcements by Hosting Controller team, that they have supported Exchange 2016. Has any one installed it yet to see how its working ? Is there any GUI changes involved since this would require a learning curve on part of knowing Hosting Controller Exchange 2016 module.
