This change ensures that alert settings in the portal accurately reflect rule configurations   made via PowerShell.<\/p>\n<p><b>When this will happen<\/b><\/p>\n<p>This change will begin rolling out on September 26, 2025.<\/p>\n<p><b>How this affects your organization<\/b><\/p>\n<p>We\u2019ve identified that a few tenants have one or more DLP rules with alert generation enabled in the Microsoft Purview portal, but the corresponding alert action was disabled or removed using PowerShell cmdlets.<\/p>\n<p>To align portal behavior with PowerShell configurations, Microsoft will automatically disable the alert generation toggle in the Purview portal for these rules. The rules will remain active and continue to enforce DLP actions, but  <b>alerts will no longer be generated unless reconfigured<\/b>.<\/p>\n<p>This change does <b>not <\/b>impact the enforcement of DLP policies\u2015only the alert generation behavior.<\/p>\n<p><b>What you can do to prepare<\/b><\/p>\n<p>No admin action is required unless you want to continue receiving alerts for affected rules. To re-enable alert generation:<\/p>\n<ul>\n<li>Open the rule in the Purview portal, make any update, and save the configuration.<\/li>\n<li>Use PowerShell to re-enable alert generation for the rule.
