Final Update: 14/05/2024 08:43:00 AM – Microsoft confirmed that the deployment of their fix has fully saturated the affected service environment, and they have verified with some affected users and through their service telemetry that this issue has been resolved.

Scope of impact: This event may impact any users who attempt to apply sensitivity labels with the new Outlook for Mac app and the Outlook for iOS and Android apps.
