Active Directory Retaining Email Address Information

We are using Exchange 2003 with a mix of 2003 and 2008 DC servers. AD replication is functioning correctly.

We used to host the DNS and email for a particular company. They are now doing their own thing. I have deleted the DNS Zone, User Account and Mailbox. We are now unable to send email to the domain and receive an undeliverable bounce from our mail server stating the email account does not exist. Everyone else externally is able to send to this domain.

I don’t believe it is a DNS issue as nslookup returns the correct information on all DC’s and the mail server.

I have tried sending using Outlook and Webmail with the same result. So I assume this rules out Outlook address caching as the problem.

The Mailbox has been purged from Exchange System Manager.

I assume some account information or the email address is residing in Active Directory somewhere but how do I find it and Delete it?

Thanks

1. Use Internet Mail Wizard to remove abc.com for Received Mail Domain
2. In Default Policy remove the SMTP:@abc.com, which is secondary SMTP domain
3. Click "Apply this policy now" and do RUS "Update Now"

However for each mail account still hv the secondary SMTP domain in the Email-Address tab, which still need to do manual remove.

you can use scripting to remove from all mailboxes.

Thank you for your help. I followed your suggestions updating RUS and using ADmodify. I also had to manually remove the Domain from the IIS MetaBase but you definitely put me on the right track.
