Hi Experts.

Im looking for the best way to tackle my problem.

I currently have an e-mail provider that we use that has an mx record pointing to my server. This is how e-mails are flowing to my server via SMTP. We are introducing a new domain name/company name change and hence i need to change my current e-mail domain eg username@orginaldomain.com to username@newdomain.com on my server.

I dont want to loose the e-mails i currently have in that inbox and still want to receive any e-mail from the original domain to the new one. I ofcourse want e-mail addresses to read like its coming from the new domain.

What is the least minimal impact i can do. I have SBS 2003 std edition with exchange 2003.

DO i delete the current mx records and apply new one at the other domain on the same ISP?

Will an exchange server that is called original server1 except mx records from a new domain name newdomain.com. What changes would i need to make at ISP and at on my server/client PC's.

If none of this makes sence or you need more info please let me know.

Thanks

All you have to do is add a new domain to the default Recipient Policy, make the domain authoritative, set it as the Default Domain and then point the MX record for the new domain to your SBS server.

Your existing email addresses will retain the old domain name but should automatically send out as the new domain name, provided they are configured to automatically update their email addresses based on the Recipient Policy.

It's fairly simple (he says!)

Hi there,

Seems easy from you have there. The question i have is do i leave the orginal mx records from the first domain pointing to the server and then add the new domians mx records to the server too? Then i update the recipient policies.

Also if anyone e-mails on the old domain name then it will still come through? but when they send it will be from the new domain providing the recipient policy is being updated.

Problems using Powershell and Active Directory?

Managing Active Directory does not always have to be complicated.  If you are spending more time trying instead of doing, then it's time to look at something else. For nearly 20 years, AD admins around the world have used one tool for day-to-day AD management: Hyena. Discover why

Yes - leave the original MX records pointing to the same place (your server).  You can point as many domains as you like to your server - as long as Exchange is configured to accept them - then it will.

If emails come through for the old domain, they will still arrive in the same mailbox they did before, but any replies will come from the new company name after you have applied the Recipient Policy with the changed primary domain.

Hope that makes sense : )

HI SOrry for delay.

I have tried this and all seems good at present.

However how can i create distrubution groups with the new domian. When i try and make a new distribution group it defaults to the old orginal domain.

I will need to contruct sales, info etc on the new domain too.

Thanks

Hi

At present i have not gone live with this so i set up a test account and applied the policy to my test account. If i apply the recipient policy as the default and then i create a distribution group, would that work then default to the new domain.

So if i created a new distribution group ie sales would that then default to the new domain ie sales@newdomain.com?

Thanks

Hi.

I went live today and once changing the recipient policy it automatically changes the the distribution e-mail groups.

Great advise, spot on! Really easy to do to.

Thanks
