Wonder, What is the difference between Read and View only permission in SharePoint?
Here is the difference between Read and View Only:
With view only permission, users can not View/Download the documents into the client applications, like Microsoft Excel! (But downloading the documents is possible, like saving the document to their local system, Right-click >> Save As. Also they can view the documents online, if office web apps is available.)
Lately, found another interesting difference: Users with View only permissions are not able to find the documents in search results! Also, if they type the URL of the document directly in the browser or click on the file name they gets access denied!!
