Hello @vuongtran,

This error is returned when all recipients you are attempting to email are filtered out as being part of the ACS Email global suppression list. Email addresses ended up on the suppression list when a delivery attempt to the email address result in a hard bounce/permanent failure. If you believe the email address is valid, please reach out to our support team and they'll be happy to assist you with investigating the issue and potentially removing the email address from the list.

Hi @kagbakpem, I'm having the same problem and your response helped me understand what's the cause. My question is: do you know if the email addresses in ACS Email global suppression list gets to be reset? I mean are they removed from this list after a time period has passed? Also, if one of my emails got on this list how would i know about that and what can i do if i'm not a Microsoft customer? (i actually am, but theoretically)

Thank you.
