A colleague of mine deleted a mail contact last month by mistake, which I recreated a day later. I do not know the old legacyExchangeDN, which I have read is what you should edit your new contact with so users do not have trouble e-mailing them.
I have one user who cannot contact this newly created contact. He receives the following error:
Delivery has failed to these recipients or groups:
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.

Any suggestions on how to resolve this? Anything I can do locally to just his machine (Outlook 2010, no NK2's). Thanks for any suggestions.
