Add Domains to Exchange 2010

We are in the process of purchasing a couple of smaller companies. I have been asked to host the domains for these new companies on our Exchange 2010 server.

So first I need instructions on adding multiple domains to exchange 2010.

Second, these companies will remain separate and on separate networks. This means the users will not be part of our domain. Is this possible? Or do I need to create a new domain in AD to go along with the new domain in Exchange?

Third, how to I allow these new users to access the exchange server from outside our network using Outlook? Do I need to set up the exchange server as a POP server? If I do what are the security implications? Will it affect our current domain users and how they access their email??

Thanks for any help.

1. Yes you could do that.

    Create a new authoritative Accepted Domain.
        This defines the second SMTP namespace that you will accept email for.
        We will use an authoritative Accepted Domains because all recipient mailboxes reside inside the local organization and do not require external routing for delivery. For more information on Accepted Domains, visit the following link:
        http://technet.microsoft.com/en-us/library/bb124423.aspx
    Create a new Email Address Policy with a recipient filter.
        Email Address Policies stamp the recipients with the email addresses that you configure.
       
There are certain things you must have in order before following this procedure. Make sure you have done the following:

    Complete the Internet Address Management Wizard.
        If you do not choose partner DNS registrar in this wizard, then you will need to manually register all of the public DNS records that the wizard would have otherwise configured for you.  This includes the MX record for your first SMTP domain.
    Register another MX record in public DNS. This will be for the second SMTP domain you plan to host.
    Verify that you can send and receive email for your primary SMTP domain.
        If this doesn’t work, it will need to be troubleshot beforehand to correct any issues that will prevent this process from being successful.
    Create some way of dividing the subset recipients from the rest of the domain so that you can target them in a filter.

For more info, you can read this article from Andrew Davis:

2. You can setup the domain trust between the 2 ADs if you want to.

3. You can enable Outlook Anywhere/OWA/POP so they can log into your Exchange server and access their mails.

Hope it helps,
