Title: A pop up window may appear when clicking on the End-user Spam Notification (ESN) “Release” button in Outlook
User impact: Users may encounter a pop up window when clicking on the ESN “Release” button in Outlook.
More info: The window will prompt affected users to ‘Select a certificate’. While we’re focused on remediation, users can circumvent the issue by clicking the ‘Cancel’ button on the window.
Current status: We’ve identified that a recent Transport Layer Security (TLS) update applied to a section of service network infrastructure, responsible for regulating authentication-related pop up notifications, is unexpectedly causing impact. We’ve developed and validated a fix to revert the offending TLS update, and have begun its deployment to the affected environment. We expect the deployment process to be in its final stages, if not already complete, by the time of the next scheduled update.
Scope of impact: Impact is specific to any user, who is being served through the affected infrastructure, attempting to utilize the ESN “Release” button in Outlook.
