New Delhi, November 13, 2026 (Yes Punjab News)
Microsoft has acknowledged that its attempts to restore affected services are not working as expected after a major global outage disrupted access to multiple Microsoft 365 applications and services.
In an update posted on X, the technology giant said it had monitored changes introduced to improve service availability but found that they were not taking effect as intended.
The company said it was exploring alternative measures to increase capacity amid persistent traffic-management imbalances.
The disruption affected several services connected to Exchange Online, with users reporting difficulties accessing email and other workplace tools. Microsoft said Exchange Online customers might be unable to access their mailboxes through Outlook on the web, desktop applications, Exchange ActiveSync or REST-based connections. Email delivery could also be delayed.
The Microsoft 365 admin centre might fail to load, while users of Microsoft 365 applications could experience problems viewing recently accessed files.
Microsoft Copilot for Microsoft 365 was also affected, with users potentially unable to load Copilot Chat, receive responses or access work-related information such as emails, calendars and files.
Microsoft Teams’ core functions, including calls, meetings, group chats and channel messaging, were largely unaffected. However, calendar-related features, the creation of live or virtual events, Copilot responses and contact synchronisation experienced disruptions.
Other affected services included Microsoft Defender for Office 365, Defender XDR, Microsoft Fabric, Microsoft Graph, Intune, Planner, Purview, To Do, Power BI, SharePoint Online, Universal Print and Windows 365.
Microsoft said its investigation was examining traffic flows and affected infrastructure to identify routing improvements and determine the causes of service failures.
The company said the findings would help it develop targeted measures to improve service stability.
