hi folks, i'm setting up accounts on a new exchange 2000 server. all is going well until i try and setup an admin@domain smtp email address for someone and the system tells me i can't as its already in use. i've checked the accounts and there isn't that address used as far as i can see. is there a tool or easy way of listing all email addresses in use on the system? or is this a system used email address? many thanks mark sudron
