I have a customer community in which I don't want those customers to be able to see each other in Chatter, so I deselected the "Customer User Visibility" option from my OWD.
I do want my users to be able to Chatter to specific internal users but only those that I choose. I cannot seem to find a way to do this. My OWD for the User object is set to Private for external access, Read only for Internal. Nothing I do seems to be doing the trick, I cannot get it to where my customer users can Chatter to specific internal users.
Any suggestions out there?
