Check whether the domain is valid one
Check the MX record.

Hi There
First thank you for your reply.
The domain is definitely valid, I try sending the user a test email using my outlook 2007 on my computer and she actually reply back to me. when I try to send another test email using the user outlook on his computer. I got the error right immediately

Whether the user is able to send message to  through OWA.

If only one user is not able to send mail to this address means, you have to trace.
Can you pls trace the message and post the result.

Hi There
I try that and the strange thing, the result came back with other email the user send or receive but this problematic one wasnt reflected at all, it was like as if the message wasnt even there at all.
I just remember when the user try to send this email, the NDR error just came right back to him

anymore idea or suggestion is really appreciate
