I ran into this same situation just last week. The best answer given was to create a new user account and mailbox for each of the old addresses. Assign the old address to this "old address box". Use Out-of-office to deliver the auto-replies from these dummy boxes. I used transport rules for forward the emails from the "old address boxes" to the real email boxes by using a cc. That way the end users could see which outside users were still using the old addresses.
Of course, I was lucky and I only had 9 mailboxes to stress over. If I'd had 1,000, it wouldn't have been feasible.

The time is coming to retire the previous one and we want to auto-reply to any message sent to the old domain telling people it's going away. How could a transport rule be applied to any message sent to a particular domain that Exchange is authoritative for? 'when a recipient address matches <old_domain>'?
