Consumer Copilot uses conversation data for model training by default (opt-out required). Mandatory arbitration and class action waiver for consumer users. CLOUD Act exposure for US-hosted data. M365 Copilot accesses email, calendar, documents, Teams, and SharePoint — significant agentic data access scope.
Use enterprise M365 Copilot with Entra ID for regulated workloads — the data protection is substantially stronger. Consumer users should opt out of training in privacy settings. Enterprise customers should review the Microsoft DPA and Online Services Terms. The Copyright Commitment for commercial Copilot is a valuable IP protection.
