Microsoft Copilot (Microsoft 365): [Copilot Extensibility] Simplified People Resolution for Custom Copilot Connectors

This feature enables connectors to resolve external identities—such as email addresses or user IDs from third-party data sources—to their corresponding Microsoft Entra ID (Azure AD) identities. By allowing flexible identity mapping, developers can: * Simplify integration workflows without needing complex Graph API lookups. * Reduce setup friction by avoiding strict dependency on object IDs. * Improve search and chat relevance in Copilot by ensuring accurate people attribution across connected systems.
