We received an ACK (positive acknowledgement) but the file did not reach the receiver. What should we do?
If you receive ACK (code 200) you can be certain that the file was successfully delivered to the next PEPPOL Access Point.
If that file did not reach the end receiver, the receiving Access Point has to be notified. Use the RecipientIdentifier to find the receiver’s PEPPOL Access Point contact details by doing a Participant Lookup. See next question for more details.
