Staff will be completing a form (let's call this Point A) where they will include attachments. For security reasons, we will not want these attachments to stay with this original list. Instead, we want the attachments to move to a list (Point B) that staff will not have access to. What SharePoint documents (forms, lists, libraries) need to be created? How would I create a workflow in O365 that would move these attachments from Point A to Point B?
I was successful in creating a Nintex workflow to copy attachments from an InfoPath form to another SharePoint Library and then delete the attachment from the InfoPath form. Depending on the form you are using for staff to complete and add the attachment, maybe some of the steps I used would be helpful. I outlined them in response to a previous question - "How to move an attachment from infopath form at time of submission using Nintex 2007."
