Hi Simon, Yes, you need to modify the default recipient policy and modify your MX records in the Internet DNS. Also, remember that modifying the recipient policy and removing the old domain name does not automatically remove the old domain name based SMTP addresses from the user objects. The users will still continue to have the old SMTP address as a proxy address. However, the new email address will become the default. If you really want to get rid of the old email addresses, then you have to remove them manually from each user object, or write script for doing that. No other changes are required. HTH.

We will register the new domain name for Internet and e-mail tomorrow. On the face of it,I believe all I'll need to do is change the Default Recipient Policy in Exchange 2003 for the "new" e-mail addresses to become live and promulgate the Exchange Store and AD. I'm assuming that old e-mails for users will still remain and their Outlook 2003 accounts will not have to be altered in any way. The ISP will point new domain name as required. Can one of you confirm (or deny) the ease of this proposed change ?
