Yammer vs SharePointOnline - prevent download and print

[Peter Peter]

Hello,

I'm trying to understand if i can prevent for 1 file or based premission levels to prevent file actions (edit/download/print/ etc..) even if they are Office documents, PDf or something else.

I found solution on SharePoint Online based on permission leves so this solution is applied to all files .

But what I need is to lock as readonly (online) 1 file on Yammer group. How can i handle it?

Maybe I didn't get for a team working why use Yammer instead of Sharepoint Online.

Sorry I'm nw about this.

Thank you
