I had two Unified Messaging server on my Exchange 2007 SP1, at one point I needed to remove one. I removed it and has disassociated it from my dial plans.
I am not sure if I actually REMOVED UM role from that server, because I needed to format the whole server anyway. Well now the server is formatted so I cannot do anything on that.
So to the point: Is it now possible to ELIMINATE from "Server Configuration\Unified Messaging" the obsolete server that still shows?
