We're using Office 365 have some public folders defined in Exchange online. Is it possible to restrict access to them? I see where I can manage folder permissions from the web version of Outlook (Admin -> Exchange -> public folders). I can add and remove users and edit their permissions, but everyone who isn't listed still has full access.
Is there somewhere where I have to set default access to none?
Are we mis-using this feature because public folders are meant to be completely public folders? If so, what should we be using instead?
