The command you have issued is trying to install the mailbox, hub transport and client access roles, all three, not just the mailbox role as you stated. Please post the complete error message. What you posted is cut off. If you are trying to add the mailbox role, then use this command: setup.com /mode:install /role:mbEd Crowley MVP "There are seldom good technological solutions to behavioral problems."
