Hi...Yes, in 4.1 the User ID agent can also query the exchange's logs for user mapping. The same 4.1 User ID agent can be used for DCs and exchange servers and the agent is installed on any Windows member server (can be DC if you choose). In the agent settings under Discovery, we would add a new server and select the server type=exchange. See attached screenshot.
Here are some docs that you can refer to.Thanks
