I have a discussion that is set to private.
On the top of the discussion, there is a hint (attached).

Well, in fact the discussion can be seen by people not only from my company (Stucel). for ex: Client company manager (who can see private stuff).

Any further help? Or did I missed something?
And, is the attached files fron private discussion stil available to everyone?

Thanks.

Thanks Ilija.
