We have a customer with an international footprint.
They currently have an exchange server in Spain (all roles on this one machine) and we are building another one for them in Australia (again all role will be installed on this one machine) for their Australian staff.
Both exchange servers will be on the same domain but on different subnets.
We would only like the Australian staff to access the Australian server, however, we would like them to be able to see all the current mailbox users and distribution groups and what not.
We would prefer for the servers to not replicate to one another.
What is the best way to go about this? Will setting up a DAG be the right thing to do?
Thanks and really hoping someone can assist.
