The recommended configuration for a four-node Microsoft® Exchange Server 2003 cluster contains three active nodes and one passive node, where each of the active nodes contains one Exchange Virtual Server (EVS). This configuration is useful because it gives you the capacity of running three active Exchange servers, while maintaining the failover security provided by one passive server.

If I understand [3 active -- 1 passive]

Logon to any node in the cluster and create MSDTC resource at the Default Cluster Group level.

for the rest of the resources at what level should I create them?

But how do I know which resources I need to assign to CORP-MSG-01 and which  to CORP-MSG-02 and which CORP-MSG-03 ?

If you have 4 node cluster in which you have 3 active and a passive node, all three active node will carry the resources as per their requirnment, if you are using three exchange servers, all three active nodes will carry three exchange resources and passive will be free on that moment but once any of the active failover the passive will take place.

I know that the Active node will carry the resources.
in 2 nodes active/passive is easy to guess, one node has Zero (0) resources and the other has all resources
in 4 nodes 3 Active/1 passive, it is not easy to tell which specific resources  are assigned to each active node.

Let's say Exchange cluster uses 20 resources total, how are those 20 resources assigned to each active node?
