Exchange Distribution Group bounce #550 5.1.1 RESOLVER.ADR.ExRecipNotFound; not found ##

I have an issue with our internal exchange 2010 where one particular distribution group is getting mail bouces.

I get:

The e-mail address you entered couldn't be found. Check the address and try resending the message. If the problem continues, please contact your helpdesk.

Diagnostic information for administrators:

#550 5.1.1 RESOLVER.ADR.ExRecipNotFound; not found ##

Original message headers:

I think this is as a consequence of me deleting a user mailbox then re-creating the dist group.

User is setup fine, can see mailbox in Exchange management console and AD, all other users etc are fine.

All help gratefully recieved.

Did you check that the problem is not in NK2 file? (Clear these address with http://www.nirsoft.net/utils/outlook_nk2_edit.html)
also you have strange FROM field
From: email> <richard@domain.com.au>
Try to send mail to this address with telnet:
Is this a mail sent internally?
It's possible that the sender has the old address book entry cached in their outlook "to" field - when you go to send the email, delete the entry from the to field and then re look it up from the address book. This is most likely to resolve this issue.
