  • Looks like it might be a LegacyExchangeDN (LEDN) issue, in that Outlook has cached the LEDN value of the old mailbox, and is still trying to send to that cached address.

    Try and clear the Outlook (NK2) cache entry for this user (ie:  when the name comes up in the auto-complete, hit your delete key to clear it out of the cache), then manually type in the smtp address.

    Another option would be if you have (or create) a new contact object for this individual in your org, in place of the old mailbox, and add the old LEDN of the mailbox as an x500 address to the new contact object.    By doing this, you will preserve the ability to reply to older emails that have been stored with the old LEDN, and negate the need to clear the cached entry for all your users.

  • Do you still have a forward lookup zone for this domain in your internal DNS?  You may still have an MX record pointing to your own server.
