Microsoft reports outage affecting Outlook, Teams and Copilot
An outage on November 12 disrupted Outlook, Teams, Copilot and other Microsoft 365 services, prompting the company to work on restoring connectivity.
Microsoft said an interruption on Thursday, November 12, impacted Outlook, Teams, Copilot and other Microsoft 365 tools, with the problem most pronounced in the Americas. Downdetector recorded more than 120,000 reports of Outlook access issues in the United States around 1:30 p.m. Eastern time, and the total rose to over 130,000 as users reported trouble sending, receiving or loading email. The site also logged about 46,000 reports for Microsoft 365 and roughly 3,000 for Teams, while some users experienced difficulties with the AI-driven Copilot assistant.
In updates posted on X, Microsoft confirmed it was investigating the incident and noted that part of its infrastructure was under higher than normal load, which likely caused the connection errors. The company said it was redistributing traffic across its network to rebalance the load and restore service. It later announced that the Teams issue had been resolved in North America, although a few users continued to report problems. Microsoft did not provide an overall estimate of the total number of affected users, and Downdetector figures reflect user reports rather than a definitive count.
