I have a list with several items on it, each has a scheduled workflow. I chose "No New Instances" for my workflow because we are retiring this list and going with a new process. When I went into each item to try to remove the scheduled workflow, none appear. Yet I keep getting emails that say the workflow schedule failed. It appears that I need to reinstate the workflow, remove the schedules, then remove the instances of the workflow.
Is there a way to mass remove scheduled workflows from several items on a list or do I need to do it manually one by one?
