Causa identificada
[Service degradation] Current status: We continue to observe sustained service recovery across the previously affected environments. Due to the severity of impact this incident caused, we're monitoring for an extended period to ensure no additional mitigative actions are required. In parallel, we're monitoring the backlog of email messages accrued during this event to ensure all process successfully before considering the issue resolved.
We're addressing all impact scenarios for dependent and related Microsoft 365 products as listed in the "More info" section below, and believe the majority of those impacted scenarios have been addressed.
More info: Features of the Microsoft 365 services below that interact with Exchange Online and email services are impacted. Elements of those services that do not depend on interaction with Exchange Online remain functional.
- Exchange Online: Users may be unable to access their mailbox using Outlook on the web, Outlook desktop (MAPI), Exchange ActiveSync (EAS), or REST-based connections, and email delivery may be delayed.
- Microsoft 365 admin center: Admins may be unable to load some admin center pages.
- Microsoft 365 apps: Users may be unable to view their recently used files.
- Microsoft 365 Apps Admin Center: Multiple services including Cloud Update, Cloud Policy, and Inventory are affected.
- Microsoft 365 Education: Features including Assignments, Reading Progress, and Speaker Progress may be impacted.
- Microsoft Copilot 365: Users may be unable to load Copilot Chat or receive responses in the web and desktop apps, and Copilot experiences may be unable to access work data such as email, calendar, and files.
- Microsoft Defender for Office 365: Some Defender for Office 365 experiences that rely on Purview DLP/Information Protection signals may experience delays or failures in policy evaluation and governance action enforcement. Admins/SOCs may experience delays or failures when accessing NHI features that rely on Data Classification Sensitivity Labels, including Tenant Metrics, Policy, and Data Usage, across the Identity, OAuth, and App Governance pages in the Security portal on Microsoft Defender for Cloud Apps.
- Microsoft Defender XDR: Users may be unable to load Microsoft Defender portal pages or solution tabs.
- Microsoft Fabric: Users may encounter failures when exporting reports with sensitivity labels to PDF or PowerPoint, when updating artifacts with sensitivity labels, or opening pbix with sensitivity label in Power

Dear Valued Customers,
We would like to inform you of an upcoming planned maintenance activity that will be performed on the following F5 service:
- NGINX One Console
Maintenance Window:
Start Time: 25 Nov 2026 18:00 UTC
End Time: 25 Nov 2026 19:00 UTC
Projected Impact:
During the maintenance window, the Console database will undergo brief restarts .
- Expected Impact: The NGINX One Console User Interface may experience transient errors or failed requests for only a few seconds during each restart .
- What to do: The Console will recover automatically. If you encounter an error, simply refresh your browser or retry your action .

Resumen del aviso oficial de Microsoft de las 20:02 UTC (14:02 hora del centro de México): los usuarios pueden no poder conectarse a varios servicios de Microsoft 365; lo afectado es lo que depende de Exchange Online (correo en Outlook web, escritorio y móvil, y entrega de correo con retraso), además de funciones de Teams, SharePoint, Intune, Copilot, Purview, Fabric y Power BI, el centro de administración y las apps móviles de Power Apps. Conforme la infraestructura se estabiliza, Microsoft sigue vaciando las colas de mensajes y reequilibrando el tráfico; los clientes pueden notar una mejora para iniciar sesión y acceder mientras la entrega y el procesamiento del correo se ponen al día. El acceso puede recuperarse antes de que el flujo de correo se normalice por completo. Todavía no hay hora estimada para la recuperación total. A las 17:57 UTC Microsoft había atribuido el incidente a una ampliación de capacidad de red y descartado un ciberataque. Próxima actualización oficial: 00:00 UTC del 14 de noviembre.

We are seeing broad recovery and stability across our services. This was a technical issue not related to cyber or AI / agents.
The incident was introduced by an issue during an earlier network capacity upgrade that surfaced following a recent network change. We have addressed the underlying issue and continue to restore service to remaining customers and regions.
Given the scale of demand, we restored services gradually, validating stability at each stage. While this took longer, it helped ensure a stable restoration. We will provide a full post-incident report once our review is complete.
