When you entrust your data to Office 365, you remain the sole owner of that data: you retain the rights, title, and interest in the data you store in Office 365. It’s our policy to not mine your data for advertising purposes or use your data except for purposes consistent with providing you cloud productivity services.

  • Privacy controls enable you to configure who in your organization has access and what they can access.
  • Design elements prevent mingling of your data with that of other organizations using Office 365.
