Microsoft Purview: Endpoint DLP – Add support of hyperlinks in warn and block toast messages for Edge browser

Microsoft Purview Endpoint DLP will support clickable hyperlinks in warn and block toast notifications in Microsoft Edge starting April 2026. Admins can link to policies, training, or support without changing enforcement. Requires updated Defender client and Edge versions; admins control hyperlink inclusion via policy settings.
