SOLVED: Video: How To Change Outlook Attachments From Linking to SharePoint OneDrive

If you are attaching files from your Office365 Onedrive Sharepoint cloud storage using Outlook 2016 you will find that it provides a lovely drop down showing you your recently edited files.  If you select files from that list and they are stored on OneDrive / SharePoint what it will actually attach is a lLINK to your files and not a copy of the actual files.
