News from the IT community on November 14th: Microsoft's official account @MSFT365Status posted a tweet on November 14th, Beijing time, stating that various services of Microsoft, including Outlook, have fully recovered and are now stable. However, Microsoft also stated in its public declaration that it is still working to restore services for the remaining affected customers and regions.
According to Microsoft's official MO1550821 announcement, this Microsoft 365 service outage began around 13:25 Eastern Time on November 12, 2026 (IT Note: around 2:25 a.m. Beijing Time on November 13), affecting multiple Microsoft services including Outlook, Teams, Copilot, OneDrive, and others.
Microsoft explained that the failure stemmed from an issue introduced during a previous network capacity upgrade, which became apparent after recent network changes, leading to increased infrastructure load. The company stated that the underlying problem has been resolved, and this incident was a technical failure unrelated to cyberattacks or AI, or agents. They apologized to customers and partners for the service disruption.
During the recovery process, Microsoft adopted a phased approach to restoring services and gradually introducing traffic, while verifying system stability at each stage. The company stated that this process took a relatively long time, but it helped to ensure a stable recovery of services.
As the repairs progress, there have been improvements in scenarios such as email access and delayed mail processing. However, during the recovery period, some users may still encounter intermittent access issues or delayed emails, and the recovery work for the remaining affected environments is still ongoing.
