Hello, I am learningExchange and working with the Trial version of EX2007 todo so. Here's what I've done so far. I have a test server installed with Server 2003 X64 and the Exhange 2007 Trial.It is the only server I have withExchange so I don't have an Edge server, just theHub Role installed. Everything is working internally... I've been following the self-pace training kit book for Exchange server andI can send and receive emails on the internal server. I cannot send or receive any email external to the server though.Now I need to work on getting external email working and suspect that I may need to reinstall the server and exchange to use an actual domain. The domain I am using now does not exist outside of my network. I already have a registered domain name that I can use, I just need to verify what I'll have to do to use it.Or can I use the existing server (AD)domain and reconfigure Exchange to use the external domain? In other words, can I leave the internal domain name (intdomain.com) as is and point (configure) Exchange to use the web domain (extdomain.com) I have registered? Either way, I imagine I'll need to open ports on my firewall so that I can point the ISP to the IP forextdomain.com. Am I on the right track here? Any advice on this?thanks!!!Dave

You will have to install exchange in the actual domain where the user's accounts located. and then configure the MX record to point to this server.Vinod |CCNA|MCSE 2003 +Messaging|MCTS|ITIL V3|

You will need to deploy exchange on your internal domain where your production users are located. Once you have done that you should deploy a CAS server and then a Hub Transport server. The CAS server should be the first server you deploy. You could do a CAS/Hub dual role on a single server, this will be just fine. Once there you can route all inbound mail to your 2007 Hub server. This may either be chaning your MX records or changing your mail routing from your firewall. You will need to create a send connector on the Exchange 2007 server for outbound mail and set the cost lower to the smtp outbound on the 2003 server. By lower you should proably do a 1 on 2007 and a 5 on 2003 server.Since the CAS server is deployed you can point owa traffic to the CAS box using the /exchange url. This will redirect users to either Exchange 2003 or Exchange 2007 (once you have the 2007 mailbox server in place) depending on the location of their mailbox. If you have to use the external domain then you will want to look at setting up a resource forest for exchange 2007, trusts will need to be established and you will need to use linked mailboxes. It gets a bit more complex when you do it this way.SF - MCITP:EMA, MCTS: MOSS 2007, OCS 2007, Exchange 2007

Exchange must run in an Active Directory domain, but I think you understand that.The e-mail domain is completely independent from the Active Directory domain name except that when you first install Exchange it takes the AD domain as the default e-mail domain to begin with. After you install, you are perfectly welcome to change the "accepted domains" and "e-mail address policies" to make them any domain you want. That is, it's perfectly acceptable to have an AD domain named "garbage.in" and an e-mail domain of "donaldduck.com", as long as you own the e-mail domain and the Internet can route to it.Some organizations use a different domain, some use the same. If you use the same domain internally and externally, which I believe is much easier for users to comprehend, then you'll want to set up a split-brain DNS. That means that although you have the same domain inside and outside, the DNS for each is completely separate. You're welcome to Google the subject and learn more about it.Does that answer your question?

Hi,Moreover. For sending message to outside world. You have to create new SMTP connector. For receiving mails you have to enalbe anonymous users checkbox in the security tab of the receive connector. There is no need to reinstall the Exchange. And as answered earlier by many that you can have your owned public domain as accepted domain in the exchange, that means that you have no need to reinstall the exchange server.Thanks.

Hi,1. MX record for the domain on public DNSthat you want to use to send/receive email. You can add the public domain which you want it to be the email suffix as a accecpt domain in Exchange Server.Managing Accepted Domainshttp://technet.microsoft.com/en-us/library/bb124423.aspx2. A record for the domain on public DNSso that outlook can use autodiscover on CAS to configure the user profile,we can use OWA on CAS to access mailbox Server.
