As the title suggests we would like to host 2 different mail stores in one server. We currently have the first storage group already and would like to add another mail store for a new domain we are creating. It will host about 150 users and mailboxes. We currently have 150 users on our first storage group. We are running exchange 2003 enterprise. Reason for this is we dont' have any available machines to host a new exhcnage installation. Can someone please point me in the right direction? thanks
