The child domain is no longer a part of our company, and the VPN circuit to them is officially down, unable to be brought back up. They have to leave their environment running as is, without seeing the parent forest. They will make a new environment for themselves, but have to preserve the existing short-term. This leaves us in a predicament as we need to remove the child domain and all Exchange related information. I have performed ntdsutil metadata cleanup to remove references to the domain, and deleted the Exchange server, but when I send messages to the old domain, I get /O=forest root/OU=child domain/cn=Recipients/cn=username in the message tracker. I am sending to the old recipient address, and if I do this via a 3rd party account, it sends fine as the DNS now points to the new server. Unfortunately, we cannot do this internally. All other email works fine. I am missing something in regards to removing the old domain from Exchange. I have verified the infrastructure master is NOT a Global Catalog, so I am at a loss as to where these files are stored. View my MCP Certifications

Try Sending it From OWA. Or Delete the autofill cache and try to Send. If my understanding is correct. Your trying to send Email to your Child Domain. Regards Satheshwaran Manoharan

This is using an Outlook 2010 client. It is not caching the user email address, and I am sending to the FQDN. It also matters not who sends the email. The result is the same. Somewhere either on a Global Catalog or within a System folder within Exchange, these email addresses are being generated or recalled from cache. I need to know how to clear them. The child domain no longer exists, so I am trying to send an email to the new email server at a new forest that happens to use the exact same format for email addresses. Essentially, it should be routing the email via the MX record, not pulling it internally.View my MCP Certifications

An additional contact object was stored. Ironically, typing in one name mapped it to another. I feel like a goob for missing this one. *facepalm*View my MCP Certifications
