Current status
Microsoft’s recovery actions are continuing in phases across the affected infrastructure. Telemetry and customer reports show incremental improvement in several services, but service health remains variable and capacity has not yet returned to baseline. Network and traffic-management actions are still active.
Microsoft is prioritising queue and backlog processing and has extended the email timeout window to 48 hours, so delayed messages are preserved rather than bounced. Some users may still see delayed delivery or be unable to access mailboxes via Outlook on the web, Outlook desktop, Exchange ActiveSync or REST-based connections.
Services that may still be affected
- Exchange-dependent features: Teams calendar, scheduling and meeting invites, and Copilot access to email, calendar and files. Core Teams calling, meetings, chat and standard channel messaging are not impacted.
Copilot: Copilot Chat may fail to load or respond, and Copilot may be unable to reach work data.
Security and compliance: Purview (DLP, sensitivity labelling, eDiscovery, audit search), Defender for Office 365 and the Defender XDR portal may be slow, fail to load, or show delayed policy enforcement.
Device management: Intune enrolment, check-in and compliance policies were intermittently impacted.
Other: Intermittent issues with Power Apps sign-in, Planner, To Do, Universal Print, Power BI and Fabric exports of labelled content, external sharing in SharePoint Online, and Windows 365 Cloud PCs using Purview Customer Key. Files held directly in SharePoint remain accessible.
Workarounds- Power Apps and Field Service: use the web versions where possible. Users already signed in on mobile should avoid signing out, clearing app data or reinstalling.
- Fabric and Power BI: where policy allows, removing the sensitivity label from the affected item lets the export or update complete.
Security. - Microsoft reports no evidence of malicious activity associated with this incident.
- Next steps
Microsoft will provide its next update by 11:30am GMT (Friday 13 November), and will publish a full Post-Incident Report with root cause and preventative actions once mitigation is complete. We are monitoring closely and will pass on further information as soon as we have it.
