We are working on setting up lazy approval. To test we create a simple workflow with a flexitask to request an approval. The process works correctly. The email for approval gets sent and when we reply back the task is updated then the task is complete. The problem we are having is that once it completes we get these email notifications every minute saying that "The task is no longer active. Another user may have already completed the task." I have tried changing different settings within the flexi task but the nothing seems to fix the issue. The only way to stop the emails is to Purge the workflow instance from Central Admin.
