Further, I want you to move one of the Mailbox server from Site B to Site A as all the users are in site A.<br />

I would also clarify that for High Availibility you are only using DAG but for CAS and HUB HA is missing.<br />

Currently we have 2 sites and all users are in Site A and Exchange servers (CAS, HUB and 2 Mailbox servers in a DAG) in Site B. Users connect to email using outlook and everything is fine.<br />
<br />
Now as a DR solution, we wanted to install Exchange in Site A and configure users to connect &nbsp;to local Exchange server.<br />
<br />
I am planning to install One server with CAS, HUB, MBX and part of DAG. Now how do i point users to this new CAS ? &nbsp;and where should i my witness server located?<br />
<br />
any answer is greatly appreciated!
