I have developed a system that starts with the end user performing some action in the GW Win32 client. That action grabs the message ID of a message, and launches an external application passing the ID on the command line.

The external app uses SOAP, and needs to be able to retrieve the message using the passed-in message ID.

But it doesn't seem to work...

Is there a message ID available via the Object API that will work via SOAP?
