Creat a policy to block file downloads from OneDrive, the policy works successfully, but the file preview cannot be viewed in the browser.
Is it possible to allow viewing the file while blocking file download?
This can be accomplished by creating an Access enforcement via Gatelets policy that has Download selected in Activities.
This will block downloads and allow you to preview files.
Currently pdf file need to be downloaded to view in browser so they will not be allowed to be viewed.\
There might be other files that are the same.
