[added: When users select a link in a Copilot Chat response, including responses from agents built in Copilot Studio, Copilot checks the link with Safe Links in Microsoft Defender for Office 365 before it opens. This check requires third-party cookies for *.safelinks.protection.outlook.com. If the browser blocks third-party cookies, for example through an organization-managed browser policy, users see an Unable to verify link message and the link doesn't open.]
