1. Yes.
2. Most of the time, it will send after retype.
3. Yes, I compared. the recipAddress are the same
4. Yes, it sent successfully.
It seems to be that somehow the outlook can tell the address is typed in or assigned by and my outlook does not like to be progammablly given sending address. How can I tell this from that MAPI interface?

>>It doesn't seem to matter whether I have 1 email address or several email addresses (several recipients). If I retype the email address, sometime the email will send. The problem apppears to be with the outlook in the machine. I have the email sent on a different computer in the past and now. But it doesn't work in my current computer. I don't know why the outlook bounces the email.
