The Office Graph powers Microsoft 365 applications like Delve. Six years after Delve’s introduction, its privacy controls are being replaced by Microsoft Graph tenant settings from May 15, 2021. The changeover is important if your Office 365 tenant includes some people who have excluded themselves from document insights. You should take action to replace the old Office Delve controls with the Microsoft Graph privacy controls.
