install exchange with hub milbox UM architecture ?
we will install a fresh exchange 2007 server in our orgnisation
we agreed on the HUB MAILBOX UM roles to be separated one in each server for performance purpose
recieving the outsidwe emails through the HUB
is there any document that shows how to install this type of architecture
i am mostly interested in the config between those roles (it should be a type of connection between these servers right) or should i say servers ?
one more question do i need win 2003 64 bit for all these roles or just in the mailbox server ?
