EXTERNAL mail bouncing from deleted and recreated account

Question
-
I do not believe this is the X.500 LegacyExchangeDN issue, as the problem occurs for external users only and the error states it is a DNS issue. The reply is going to <ADDomain>.local, so that shouldn't resolve properly. My question is why the .local address is being used and how to fix that.
Here is the error report from a bounced message:
IMCEAEX-_O=FIRST+20ORGANIZATION_OU=EXCHANGE+20ADMINISTRATIVE+20GROUP+20+28FYDIBOHF23SPDLT+29_CN=RECIPIENTS_CN=<User Name>+20<UserLegacyExchangeDN>@<ADDomain>.local
Technical details of permanent failure:
DNS Error: Domain name not foundThanks for any ideas,
Eric

Amy,
We are running Exchange 2010. While the behavior I saw deviated from all of the reports I came across, adding the X500 address to the user and correcting the LegacyOutlookDN apparently fixed the problem.
Thank you.

Does this error only occur when the external party attempts to reply to an email that was sent prior to the deletion of the internal AD account or is this error also received when they create a new email?Thursday, December 26, 2013 3:03 PM

Unfortunately for my curiosity, but good for my user, is that the X. 500 entry or one of the other repairs I tried fixed the problem. I also had tried reapplying the Addressing Policy and maybe a few other things.
Thanks for giving it some thought.

Hi Eric,
I would like to verify your Exchange version at first.
If you use Exchange 2003, please check the recipient policies. Here is a thread for your reference.

If you use Exchange 2007 or Exchange 2010, please check email address policy. Here is an article for your reference.

Hope it helps.
