Returns mailbox settings including timezone, language, and auto-reply (out-of-office) status
AI agents call get-mailbox-settings 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 configuration data from a mailbox without side effects. While the data returned (auto-reply status, timezone preferences) could be sensitive personal/organizational information useful for reconnaissance or social engineering, the tool itself performs no write, execute, or destructive operations.
From the tool's definition Tool returns mailbox settings (timezone, language, auto-reply status) with no described capability to modify data. The verb 'returns' and listing of read-only settings confirms retrieval-only behavior.
