Have flow check for a duplicate file name prior to attempting to adding attachment in SharePoint? The problem is if duplicate file already exists in SharePoint, flow will not add the file. I understand there are options e.g. (turning on versioning in SharePoint, and making a file name unique by adding the date/time to the name), however, what I would really like to do is first check for a duplicate file name in SharePoint, and then if found, add a time stamp to that one file. Thank you!!
