Multiple Exchange 2010 email provisions on a single domain.

Hello all again,

I have been tasked  to provision different email addresses for business units within my organization.
As an example: Currently using for all our email. However, they are also wanting The issue is we do not have any sub-domains for Miami. We have a single domain Forest without any sub-domains. Thus, is there a way to accomplish this keeping in mind yet another hurdle: Miami is part of our domain, and they want the email to read separately as
Building a child domain isn't an option and note: since is just a hopeful extension there is no MX record for it.
Any ideas, thoughts, or help would be appreciated.

Externally you would create another MX record to point the email to your exchange (along with DNS).

You would then add an accepted domain to your exchange server and you can create a policy or either assign the address to the users mailbox etc so they can recieve both and so forth.  Add an accepted domain to your exchange basically states it will accept email from that address in which your case is etc.  So your exchange will then start recieving both @kansascity and @miami.

 Let me see if I follow because I am still new to Exchange. We own the domain so all I need to do is when I set the MX record is to point it at the same settings as the MX record?
Next I add the new domain to be accepted in my Exchange, and that is basically it. So, I would be able to assign mailboxes to be either or or even both?

If I am off let me know.

The steps above are correct.

- Create MX record for pointing to the external IP of your current Exchange server
- Add the Accepted Domain (in Exchange)
- Create an Email Address Policy for users that will use the ( domain)

There are several different ways you can apply email address policies to user accounts. See the below link for details...
