Current Update: 15/07/2025 09:10:00 AM Microsoft are continuing to monitor the rollout as it fully deploys to all impacted environments. They’re currently seeing the rollout has reached most impacted environments and they’re now initiating the next phase to enable the code in a small subset of infrastructure to test its stability and ensure that it successfully resolves impact. They’ll provide an update on this testing and validation, as well as any timeline for the complete rollout to all impacted environments during their next update.

Scope of impact: Any user attempting to use event-based retention in Data Lifecycle Management and Records Management may be impacted.

Root cause: A recent change intended to improve performance to a section of infrastructure responsible for Microsoft Purview functionality has degraded this infrastructure and is resulting in impact.
