Copilot terms now require a Microsoft account and exclude work or school accounts

AI training: narrowed✓ Machine-checked

The Copilot terms were renamed 'Supplemental Terms' and now also cover Copilot Chat in Microsoft 365 apps, but not users signed in with work, school or organizational accounts. A Microsoft account is now required, and a new rule bans hiding or altering content credentials that mark AI-created content. Advertising is now stated to apply if you lack a paid Microsoft 365 subscription. The Copilot Health terms and their no-advertising, no-AI-training statement were already in the old version.

Taken from you

  • Using Copilot without logging in is no longer allowed; a Microsoft account is required
  • Cannot hide, remove or alter content credentials or marks showing Copilot created your content
  • Cannot mislead others about whether you used Copilot to create content

Won back

  • Advertising now stated to apply only if you lack a paid Microsoft 365 subscription
  • The Report a Concern page is now also named as the route for harmful content in Copilot.
