Office 365 gives users the ability to synchronize their LinkedIn contacts to Office 365. Those contacts are listed as contacts in People in Office 365. Many security conscious organizations want to prevent data leakage and the accidental forwarding of emails outside the organization. The though is that if these contacts are not synchronized, then the chances of accidental forwarding will not happen. I will leave it up to you to decide, but I have had partners ask for this to be disabled.
