changing the domain name for mailboxes

We are changing our domain name from user@olddomain.com to user@newdomain.com and I have a few concerns. My plans are as follows and if I missed something I'm hoping you guys/gals will chime in.

1. I was going to change the Default Policy by adding @newdomain.com to the policy and unchecking the old policy. I believe this will create email addresses for everything with the new policy, retain the user@olddomain.com address as a secondary address and give new accounts only the user@newdomain.com address.
2. Not sure about the webmail address. Currently it's webmail.olddomain.com and I want it to be webmail.newdomain.com

I've done some testing on this by creating myself an email address at @newdomain.com and I'm able to receive mail and this shows as my return address, but I want to see if I'm missing something before I "throw the switch" and do it globally.


Thanks,
Bobby

First thing then you need to add an accepted domain: newdomain.com in order to be able to receive emails.

Did you change DNS records ? MX and A records for example MX records to point to mail.newdomain.com and  A record mail.newdomain.com to point to mailserver IP ? this will also solve your owa problem.

Sorry, let add more info for you...yes DNS has been setup and since I manually created myself a new email address with the new domain, I am able to receive email sent to it. My concern is how do I change the webmail URL from the existing address to a new one, yet have the ild also work. So basically I'm asking how to add a second URL for Webmail.
