Deletes a mail folder
AI agents call delete-folder to permanently remove resources in Outlook MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Deleting a mail folder is a destructive operation that cannot be undone. It removes data irreversibly (the folder and potentially its contents). This is more severe than Write (reversible modifications) or Execute (context-dependent effects). An AI agent misusing this tool could delete entire email folders, causing significant data loss.
From the tool's definition Tool name is 'delete-folder' and description states it 'Deletes a mail folder'. The verb 'deletes' combined with 'folder' indicates irreversible removal of data structures.
