Retrieve x500 address after PST migration

Hello all,

I had to perform a rather rough Exchange migration after a new client came to us with a failed Exchange server.  The former server was Exchange 2003 and there was a motherboard failure, so we could not get the server up again.  I was able to extract PSTs from the information store and import them into the new Exchange 2010 store via Outlook.

Like so many others in this situation, we are discovering that when users reply to messages sent to the former email system, or contacts from the autocomplete nk2 file, we are seeing bounce-backs complaining of the user being unknown.  Specifically, here is one of the errors from a bounce-back:

---------
'<Recipent name>'
The e-mail address you entered couldn't be found. Please check the recipient's e-mail address and try to resend the message. If the problem continues, please contact your helpdesk.

IMCEAEX-D@<clientdomain.org>
#550 5.1.1 RESOLVER.ADR.ExRecipNotFound; not found ##
----------

I go to a sent message and try to click on the recipient of the sent message to find out what is on-file for an email address and it gives me an error that says:

----------
"Cannot perform the requested operation.  The command selected is not valid for this recipient. Information was given to the Microsoft Exchange Address Book which requires a newer version of the Address Book. Upgrade Microsoft Exchange.
----------

I have read that if I can find the old x500 address I can add it as a custom address to each user's email address profile so that it works as a proxy.  The problem is, I cannot find the former x500 address because the former server is gone, and in order to install the new server into the existing AD we had to remove the former exchange attributes from AD manually, and I don't think any traces of the former server have been left behind , but I suppose I could be wrong.  We also had to elevate the AD functional level from 2003 mixed mode to 2008R2, if that is at all useful to know.

Anyone have any suggestions on how I can correct this problem so that users can respond to messages older than last weekend?  The .NK2 problem would be nice to solve as well, but I am focusing on the replies first.  Thanks!

Since the problem only occurred when replying to emails from the previous Exchange server, we decided it would be better to train users to correct the email address for replies to older emails.  Replies to current emails don't have this problem, so whatever.
