Hello,
Few of our users are receiving below NDR;

IMCEAEX-_o=ExchangeLabs_ou=Exchange+20Administrative+20Group+20+28FYDIBOHF23SPDLT+29_cn=Recipients_cn=9056efeaf98e47a4aa7ebbb11658591c-userlastname+2C@domain.com

In above NDR, user's last name is there with the prefix numbers.

IMCEAEX-_o=ExchangeLabs_ou=Exchange+20Administrative+20Group+20+28FYDIBOHF23SPDLT+29_cn=Recipients_cn=17b3e6e8eef040bba4f480fe2f11af09-userlastname+2C+20userfirstname@domain.com
#550 5.1.1 RESOLVER.ADR.ExRecipNotFound; not found ##

In above NDR, just user's last name and first name is there with the prefix numbers.

I reviewed articles on internet stating it is an issue with "legacyexchnageDN". It says to adjust the legacyexchangeDNS value in the UserAD properties by ADSIEDIT to the same value mentioned in the NDR.

But in my case this NDR contains numbers in prefix.

Recipient Policy for our domain is FLastname@domain.com (First initial followed by lastname)

Please let me know how to resolve this.

Thanks.

Does this happen for the same user on all machines or just one machine?

Did the users name, email address or anything else change recently.

In the past I have seen this error due to a bad autocomplete entry.
If you go to the affected machine start typing the name so it autofills and delete it from the list.
Then create a new message picking the person from your address book instead of the autofill.


This should fix it for you.

1) Same NDR issue from other machines.

2) Username and Email address WAS NOT changed for the user of 1st NDR
    Username and Email address WAS changed for the user of 2nd NDR.

3) Deleted the cache entry, sent mail by taking name from Address book, but same issue.
