After deleting a workflow and removing the Nintex Task Outcomes content type created by the workflow, there is no option to also remove the site columns that is created as part of the Nintex Task Outcomes content type.
Instructions
When creating the Nintex Task Outcomes site column to store the choices the “AllowDeletion” flag/property on the site column is set to FALSE to prevent accidental data loss of customer’s choices. This setting needs to be changed to TRUE before attempting to delete the site column. This can be done via powershell.
