Scraping Outlook web inbox with Claude in Chrome javascript_tool

The Outlook web message list (outlook.cloud.microsoft/mail) is virtualized: [role=listbox] and its parents are not the scroll container. To find it, filter divs with scrollHeight > clientHeight and overflowY auto/scroll that contain the listbox, then step scrollTop by about 500 px and collect [role=option] innerText into a window array. If javascript_tool output contains URLs with query strings, the whole result is replaced by '[BLOCKED: Cookie/query string data]'. Before you return text, replace https?:\S+ with a placeholder and replace = & ? with spaces. Combined with the 1000-char cut, return about 12 rows per call, or save a window._open(needle) helper that clicks an option and stores the reading pane text, then read it in small slices.
