I have use case here that I have outsourced the part of my project and I do not want developmental partner to see email address of my customer or my customer to see their email address either.
To achieve this, I have revoked the Browse users and groups permission from the Global Permissions setting for the assigned groups, that is assigned to both of them
But when I logged in as other users, users still see the other users and email address.
How can I restrict this?
