Admin updates to the Microsoft Purview compliance portal may not be implemented as expected

Title: Admin updates to the Microsoft Purview compliance portal may not be implemented as expected User impact: Admin updates to the Microsoft Purview compliance portal may not have been implemented as expected. More info: This may have impacted changes to the following policies made from Wednesday, February 25, 2026, through Thursday, March 5, 2026: - Sensitivity Labels - Microsoft Purview Data Loss Prevention (DLP) policies - Holds, including custom holds - Retention Policies - Insider Risk Management - Optical Character Recognition (OCR) policies Additionally, admins may not have been notified if the policies didn't sync as expected. Final status: We've determined that a recent service update had introduced an impacting calendar configuration issue that was preventing admin updates from being implemented via the Microsoft Purview compliance portal. After our deployment of a fix to correct the isolated calendar configuration issue, our internal service telemetry validated that impact had been remediated. Scope of impact: Admins who attempted to update policies in the Microsoft Purview compliance portal may not have been able to do so. Start time: Monday, February 23, 2026, at 8:00 AM UTC End time: Thursday, March 5, 2026, at 10:50 AM UTC Root cause: A recent service update to improve our event driven programming produced an impacting calendar configuration issue. Next steps: - We're further analyzing the offending service update and impacting calendar configuration issues to help us improve our pre-deployment testing and validation processes. This is the final update for the event.
