In this article lets have a look at installing exchange 2016 in exchange 2010 coexistence.
Before proceeding with the installation i would like to give a small summary and features of exchange 2016 not a detailed one since there are good articles on the new features of exchange 2016 written by senior MVP’s.
Below are new features of the product :-
One Mailbox role with all the functionality
The mailbox server in exchange 2016 hosts all the components – Client Access protocols, Transport service, Mailbox databases, and Unified Messaging.
The main reason of this design is to simplify the architecture, reducing the hardware dependency by running on a healthy CPU power which is less expensive, and easier way to isolate any issues if we come across.
Edge transport role is coming with RTM
Considering the legacy RPC technology all Outlook connections will be MAPI over HTTP.
By default this is not enabled if you are installing on Exchange 2010/2013 coexistence and you can enabled them.
But if you have this already enabled in Exchange 2013 then it will be enabled.
If you are installing only exchange 2016 then its enabled mapi over http as a default
For further information on the architecture you can go through the below excellent series from MVP Prabhat and tech-net
Now lets go through the installation part
