Microsoft said on November 12, 2026 that efforts to repair a major outage of Outlook were not going as expected and the firm was seeking alternative solutions as users around the world were left without its crucial services. The hours-long disruption, which Microsoft attributed to "elevated load" on its infrastructure, has hit email as well as products such as Teams and the AI assistant Copilot.
