Hi Chris,

I asked the user to forward the email with the error message to me, but it only has this in the body:

> On Jan 20, 2016, at 1:33 PM, *** Email address is removed for privacy *** wrote:

Or is this NDR something that I can generate myself from the admin portal?

Thanks,

Patricia

Hi Patricia,

To do further investigation, we need to analyze the whole NDR to check where the emails are blocked. So can you send the whole NDR to us? For more information about NDRs, please refer to the article that Chris mentioned above (Non-Delivery Report).

Thanks Gray, I request the user to send me the bounce email message that she got that contains the Non-Delivery Report details that you need. I'll let you know when I got it from her. Thanks again. Patricia

Hi Patricia,

Thanks Claud. I'll wait for an update. Patricia

Hi Chris or Claud,

Can you inform if there is any update on this issue as I provided the whole NDR on Jan 25. Thanks. Patricia

Hi Patricia,

I've contacted the back end engineer and got the updates that the issue has been fixed.
Could you please confirm it?

Thanks,
Claud

Hi Claud,

Thanks for the update. I sent an email to the suer to confirm that. I'll let you know when I hear back from her.

Hi Claud,

Thanks again. Very much appreciated!
