Don't show senders of received emails from receiver found by search in "Works with" area (-> NSA style)
Currently you disclose the senders of emails an Office 365 user A has received when another user B searches the user and selects it.
The user B sees any email sender user A has received an email from.
That way the user easily can derive the communication relationships of other users, what may be with intent, but is highly unwanted in our area (Germany), who is not so fond with NSA's style of data security.
Please make this feature detachable. ("Works with" is named "Arbeitet mit" at me, hope it spells "Work with" at you).
