Microsoft’s use of so-called ‘Connected Experiences’ has come under scrutiny following claims it collected user-generated content to train its AI models. The latest claims stem from an X post by @nixCraft, who accuses Microsoft of turning on an opt-out feature that automatically scrapes Word and Excel documents for AI training.

Microsoft has denied claims that it uses Microsoft 365 apps (including Word, Excel, and PowerPoint) to collect data to train the company's artificial intelligence (AI) models.

This week, Microsoft refuted reports claiming that it is training its Copilot AI on data customers store in Microsoft 365.
