Is there any way to keep users other than members of Enterprise Admins from adding themselves to the Organization Management role group in Exchange 2010? For example, I'd like to keep Domain Admin members from doing this. Thanks, Craige

You dont trust them?

I just don't want those who haven't been fully trained in Exchange yet adding themselves to this role. They need domain admin for other things, but as a function of their job, they don't necessarily need unfettered rights to the entire Exchange system.

You really cant prevent that in the end. If they are doing that and accessing Exchange, then this is really mangement issue, not a technical one.
