Understanding security and privacy of Delve and intelligent experiences in Office 365

I totally agree that once users are educated, their concerns with regards to what Delve surfaces gradually diminishes. However, many companies don’t invest adequately upfront in training their users. Then all it takes is one senior manager to stumble across sensitive documents their co-workers are currently working on in Delve, and thereafter Office Graph will be disabled indefinitely.

From a customer perspective (in my experience) they would far rather mitigate risk when enabling Office Graph initially without having to make an all or nothing decision. In such scenarios, tweaking the HideFromDelve managed property in the search schema should be a very simple exercise - I say “should” because I haven’t personally tested it. Theatrically it “should” work 😊!

With this approach you could also implement the completely opposite intended behaviour to surface only “approved” content in Delve by adding the HideFromDelve site column to all document libraries where you "want" to surface content in Delve, with the default value for the HideFromDelve site column set to "False" instead of True.
