Consider the following scenario:
- You have a send pipeline that uses the MIME/SMIME encoder pipeline component in Microsoft BizTalk Server 2006 R2 or in Microsoft BizTalk Server 2009. You set the signature type of the MIME/SMIME encoder pipeline component to ClearSign.
- You create a BizTalk orchestration that runs the send pipeline to sign outgoing messages.
For example, you use an expression to call the send pipeline of a message assignment shape in the orchestration. For more information, see to the "More Information" section. - You install Microsoft BizTalk Server 2006 R2 Service Pack 1 (SP1). Or, you upgrade to Microsoft BizTalk Server 2010.
- You run the BizTalk orchestration.
There was a failure executing the send pipeline: "<pipeline name>" Source: "MIME/SMIME encoder" Send Port: "<send port name>" URI name" Reason: Unable to sign outbound message because the encoder could not find the signing certificate in the "Current User\Personal" certificate store.
