Reason: Unable to remove the message non-repudiation details of an incoming message.

You can use some troubleshooting method to get more detailed information about this issue, such as: BAM, etc, it will be helpful to troubleshoot

Can you check in the eventvwr if you are getting any other error message as well.

Usually the non-repudiation information is a certificate or digital signature so that it cannot be denied that the message was sent from some person or party. Here is a good link on the RNIF protocol that mentions it uses S/MIME with digital signatues for non-repudation: http://www.rosettanet.org/cms/export/sites/default/RosettaNet/Downloads/whitePapers/RNIF2x1x1x.1.pdf.


It sounds like a message is coming in and the RosettaNet accelerator is having trouble determining who the digital signature belongs to so it cannot route the message successfully. Are you sure that you have setup the certificates for all of your trading partners for received messages? Also, I noticed the URI is running asynchronously. Have you configured the party properties to be aware that an asynchronous response is signed?
