Newshot Microsoft says Outlook and other services are recovering and stabilizing, some users still awaiting restoration
IT之家 November 14 news: Microsoft's official account @MSFT365Status posted a tweet on November 14 Beijing time, announcing that its Outlook and other services are showing comprehensive recovery and stability. However, Microsoft's public statement also said it is still restoring services for remaining affected customers and regions.
According to Microsoft's official MO1550821 announcement, this Microsoft 365 service disruption began around 13:25 US Eastern Time on November 12, 2026 (IT之家 note: around 2:25 AM Beijing Time on November 13), affecting Outlook, Teams, Copilot, OneDrive and multiple other Microsoft services.
This disruption initially involved Teams, and Microsoft later confirmed that Exchange Online and Outlook were also affected. The disruption also impacted office functions beyond email. In services including Teams, SharePoint Online, and Microsoft 365 Copilot, some functions that rely on Exchange were affected.
Microsoft explained that the disruption originated from an issue introduced during a prior network capacity upgrade, which surfaced after recent network changes and caused increased infrastructure load. The company said the underlying issue has been resolved, this incident was a technical fault unrelated to cyberattacks or AI and agents, and apologized to customers and partners for the service interruption.
During the recovery process, Microsoft adopted a phased approach to restoring services and gradually introducing traffic, verifying system stability at each stage. The company said this process took a relatively long time but helped ensure stable service recovery.
As repairs progressed, scenarios such as mailbox access and delayed email processing have improved. However, during the recovery period, some users may still experience intermittent access anomalies or email delays, and restoration work for remaining affected environments
