I have a sbs2003 server and I need to change the email domain name.  For example from the current 123.com to the new 1234.com  If change the mail settings through ciecw to the new domain will I lose any informaion from the old emails? After the change is made I can configure exchange to accept  the old 123.com What are the best practices to make this transition?

Are you still wanting to get any new 123.com emails?  You can just add the new 1234.com in exchange as a new domain to accept email for it.

Yes I did that but I want to drop the old domain in a month or so. So I need to make the pirmary the new domain. I was just worried about losing any data in the switch.

When the user sends an email I want the reply address to be the new domain.

No e-mail should be lost, just add a recipient policy to Exchange and it can handle e-mail for both domains (I wouldn't remove the old one - unless you WANT people to get bounce messages that the address/domain doesn't exist).

You won't lose any data.  I recently did this for a client and it went really slick.  All you need to do is add the domain and set it as the primary.  Everyone's account should update to use the new domain as the default address when sending out and still receive the old domain's email.
