We are using Exchange server 2003 in our conpany. I would like to share our e-mail address list for the other conpany. as far as I know I can do that with LDAP server to find our addreses list.Other conpany did this issue in their server than I added that server in my outlook 2007 than I can search a name in their address. How can I do this issue? thanks in advance..
