I am trying to fix a workflow that I had previously tested and was working. The workflow sends an email to a SharePoint group which includes multiple users. On this particluar workflow I am getting an error that terminates the workflow. I have attempted to use a brand new SP Group but that is not working. I have verified we have access to all resources the workflow will touch and the users are part of the group that owns the SP Group. Any ideas or suggestions? Here is the error.
