I need to send a workbook to people outside of my organisation, however due to the nature of the database we dont want them to be able to save a copy, edit the text or print it. I've tried 'restricting' it, however that appears to only work for people within our organisation. I did a password protection on editing, however everyone (internal and external) were still able to save their own copy (which they could then edit and print).
It has to be sent as an attachment. I can not link it to one drive.
Does anyone know of a way to restrict it to purely read only for external users?
Thanks in advance, any assistance would be appreciated.
