I created an intranet to sharepoint (online) , which provide info and documents to the users.
I added the users as visitors (so they can't do any modification). I would like to change the permissions to the documents.
I need the users to be able to upload their documents. There is any way to be able to upload data to documents and the same time to be visitors to site so they will not be able to apply any modification?
How to do this ?
