Microsoft Teams

Microsoft says Microsoft 365 Copilot prompts, responses, and Microsoft Graph data are not used to train foundation LLMs.

Optional feedback may be used to improve Microsoft 365 Copilot, though Microsoft says it is not used to train foundation LLMs.

Microsoft says Copilot keeps data within Microsoft 365 service boundaries and applies existing organization controls.

Microsoft 365 Copilot can access emails, documents, chats, meetings, contacts, and Graph connector data the user is permitted to view.

Microsoft uses cookies and similar technologies for personalized ads and analytics on Microsoft sites.

Microsoft privacy statement includes advertising and marketing uses.

Controls may sit in Microsoft account, browser, or organization admin settings.

Teams workplace data should be separated from broader Microsoft consumer advertising contexts.

Deleted or edited messages may remain discoverable for compliance until retention expires.

Strong retention controls depend on Microsoft 365 licensing and admin setup.

Teams retention policies can retain, delete, or retain-then-delete chats and channel messages.

Files and meeting recordings may require SharePoint or OneDrive retention policies.

Organization admins have strong retention, eDiscovery, and export controls.

End-user controls are limited by tenant policies and admin configuration.

Deleted or edited messages can remain in compliance storage.

Microsoft provides privacy request paths, but workplace accounts are organization-managed.
