Supports OData filtering, search, pagination, and sorting. WHEN TO USE: User asks "show my emails", "do I have unread messages?", "what emails did I get today?", "show emails from John", or "list my inbox". FILTER EXAMPLES: "isRead eq false" (unread only), "from/emailAddress/address eq 'john@example.com'", "receivedDateTime ge 2026-02-01T00:00:00Z" (emails after a date), "hasAttachments eq true" (only emails with attachments).
