Do you have your inbound mail set to map "Notes"? It sounds like the process is trying to map the subject but it doesn't know where to look to map it. You will want to go into your Inbound and double check the mapping is still there. Also, this might be helpful for your other error message:http://community.landesk.com/support/docs/DOC-15449
Thanks for your reply.
Yes, my notes are mapped and I am able to append a note using e-mail at the start of my process, when the status 'Add Note' is an optional action instance.
However, when I define 'Add Note' as a manual action, the mappings can't resolve to the new point in the process workflow. My event logs actually shows the subject and body mapping correctly at any point in the process.
It's just when I define the manual action 'add note' that I run into issues. Unfortunately, I want to have this as a manual action so I can do things like alert my users that a ticket has been updated, or be able to auto-close a ticket using a note.
