This feature enables admins to quickly and efficiently delete sensitive or overshared content during investigations, directly within the product   experience. The purge action complements DSI\u2019s AI-powered capabilities\u2015such as categorization, AI search, and risk analysis\u2015helping organizations reduce data exposure and mitigate leaks faster.<\/p>\n<p>This message is associated with Microsoft 365 Roadmap ID <a href=\"https:\/\/www.microsoft.com\/microsoft-365\/roadmap?filters=&amp;searchterms=542930\" target=\"_blank\">
