Microsoft unlocks Copilot AI inside Office apps for all businesses

"Microsoft is promising that Copilot inside Office apps will change the way documents are created and edited. The Copilot, powered by GPT-4 from OpenAI, will sit alongside Microsoft 365 apps much like an assistant, appearing in a sidebar as a chatbot. It will also be available to summon inline, allowing users to generate text in documents, create PowerPoint presentations based on Word documents, or even help use features like PivotTables in Excel."

How much of these uses of Copilot causes a business' data to be sent to Azure or wherever the Copilot is running?

If the business data has compilance requirements (HIPAA, GDPR, etc.) is Copilot able to meet those requirements to prevent inadvertent disclosure, training on sensitive data, or similar?
