OK, I’ll proceed with creating a new message. I thought for a little bit that I could Clone the message, but it doesn’t appear that’s possible with a received message, just a new one.
On a sire note, the URL you passed in the previous message doesn’t seem to work, and a search in the ObjAPI didn’t return an AddExisting… either. My guess is that its not active on their site yet.
Thanks for your help with this !
