My organisation has Exchange 2007 e-mail server, and now, we want to host e-mail service for other organisation ( I added new Authoritative Active Domain, but when adding a new mailbox, there is no option to chose new SMTP domain name, and I can't add new user with SMTP domain

Probably I misunderstood something while reading posts on Internet, but can someone help please?

It sounds like you need to add the new domain to your E-mail Address Policy, under Organization Configuration>Hub Transport>E-mail Address Policies.

So when I add new E-mail Address Policy, the final thing I need to do is to contact ISP of organisation which want E-mail service, for new MX record in DNS if I'm not wrong? Thx for answer! – Mr.M Apr 16 '12 at 11:03
