Lists recent emails from your inbox
AI agents call list-emails to retrieve information from Outlook Assistant without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves or queries email data with no side effects. It performs a read-only operation on inbox contents, matching the 'Read' category definition.
