Multiple Email Addresses/Domains

[Evil8]

We have a Windows 2003 Small Business Server with Exchange Server running our domain mycompany.com. Workers are all using Outlook 2003 for client email.

We are splitting out part of our business and those people will be using a new domain name newcompany.com. We have the obvious change over period where they are going to need to receive email from both addresses, but generate new emails only from the new domain. How should I best set this up? Will email aliases work or do I need to set up Exchange for multiple domains? Will one Outlook account receive emails sent to both addresses?

Also, at this time, the domain name is "parked". What must I do to make it live for emails to work?

Thank you so much for your help, I kinda lost here as I've never had to work out something like this.

I'm assuming that those users will be migrated to a new Exchange server? If so, once you separate them, create contacts in your SBS for those users, and set the forwarding address to their newcompany.com address.

If you're not separating them to a different server, add a new accepted domain for the new domain name, and create a new address policy that is scoped to those users and applies the new email address and sets it as the default.

My bad - I was thinking Exchange 2007/2010. For 2003, just a new email address policy that's scoped to those users is needed. An accepted domain isn't available in 2003.

You'll also need to setup the MX records for that new domain to point to your public IP address, just like the ones for your current domain.

58sniper - Thanks for your help. Putting them in a new server would have been nice, but the whole company here has less than a dozen employees. We will keep 6 in the old domain and 4 in the new company.

By a new email address policy do you mean adding the new SMTP address in the E-Mail Addressess tab in the Recipients container properites in the Exchange Manager?

Okay another piece to this puzzle - I'm not sure this changes anything though. Our email is going through the third party spam filter frontbridge. I now have the MX records of both domains pointed to mail.global.frontbridge.com and I have an email out to them to add the new domain to our account. I added the new email address for smtp as I posted above, but at this time I don't have the box checked in the email address policy page. I want to make sure I'm doing all the correct things.

Question - There is also an X400 policy listed there for the current domain. Should I also add one for the new email domain?

Also - I have OWA and Active Synch working for the current email domain. Will it automatically work for the new email domain? Am I wrong to think that the iPhone Server setting should not change, but do the users will have to change the Domain setting?

Am I missing anything?

Thank you so much for your time.

Another question -

To set this up so that users' can choose the correct outgoing email address in Outlook 2003, I understand that I need to make changes in the DNS Forward Lookup Zone and add the newcompany.com under the server. My question is now there are 2 records, an SOA and an NS record. Right now they are set "same as parent folder". Does anyone know if any additional changes need to be made here? Obviously I can't test yet as MX records haven't propigated and the spam hosted service hasn't responded to my email about the new domain name.

Create a NEW policy, since the new domain only applies to some users. Set the new domain as the default.

For OWA and EAS, you'll need the appropriate DNS records, but, yes, it will work.

Outbound mail uses the default SMTP address specified in their account. Search this forum for ideas on how to work around that.
