Problem is that in a CSV file, CRLF duo are used to separate the lines. The problem here is to known when it is a end of line CRLF and a end of line in your "message" field.

Your best bet would be to replace your CRLF inside your "message" field by any other string like {CRLF}, in Workflow using Regex and then use my solution in PPress.
