跟进：微软宣布全球故障全面恢复，为其余受影响客户与地区恢复服务

微软11月14日上午宣布，这场自11月12日起影响全球的 Microsoft 365 大规模故障已经全面恢复，公司已完成对底层问题的处理，并为其余受影响的客户与地区恢复了服务。微软在 Microsoft 365 状态页与官方账号的更新中说：「我们已经完成处理这一事件底层问题的工作，并为其余受影响的客户与地区恢复了服务。」这意味着 Outlook、Teams 与 Copilot 等服务持续两天多的中断就此结束。

微软再次为这次中断向客户与合作伙伴致歉。公司表示，各服务已呈现广泛恢复与稳定状态，恢复工作采取分阶段推进、每一步都先验证稳定性，因此耗时较长，但有助于确保恢复平稳。微软承诺在审查完成后发布完整的事件复盘报告，管理员可在 Microsoft 365 管理中心以事件编号 MO1550821 追踪后续更新。

关于成因，微软此前已说明，这次故障是技术问题，与网络攻击无关，也不是智能体所致。问题出在早前一次网络扩容升级中埋下的隐患，在近期一次网络变更后浮现，核心受影响的是 Exchange Online 的邮箱与日程功能，与之无关的应用当时仍可正常运行。

这次故障始于11月12日约17时25分（格林尼治时间），用户报告随后迅速攀升。在线故障追踪平台 Downdetector 收到来自70多个国家和地区的报告。Microsoft 365 应用在全球有超过4.3亿用户，企业与政府机构的电邮和线上协作在这两天里大面积受扰，南加州 Rancho Palos Verdes 与 Barstow 等市的市政电邮也一度中断、其后陆续恢复。微软11月13日曾表示全面恢复尚无时间表，11月14日上午的这次宣布为整个事件画上句号，后续只待完整复盘报告公布。

Follow-Up: Microsoft Says Services Fully Restored After Global Outage, Remaining Customers and Regions Back Online

Microsoft said on the morning of November 14 that the global Microsoft 365 outage that began on November 12 has been fully restored, announcing that it had completed its work to address the underlying issue and restored service to the remaining impacted customers and regions. In an update on its Microsoft 365 status page and official account, the company said: "We have completed our efforts to address the underlying issue of the incident and restored service to the remaining impacted customers and regions." The announcement ends more than two days of disruption to services including Outlook, Teams and Copilot.

Microsoft again apologized to customers and partners for the disruption. The company said it was seeing broad recovery and stability across its services, and that it had restored services gradually, validating stability at each stage, which took longer but helped ensure a stable restoration. Microsoft said it will provide a full post-incident report once its review is complete, and administrators can follow further updates under incident number MO1550821 in the Microsoft 365 admin center.

On the cause, Microsoft had said earlier that the incident was a technical issue, not related to a cyberattack or to AI agents. The problem was introduced during an earlier network capacity upgrade and surfaced following a recent network change, with features tied to Exchange Online, its cloud-based email and scheduling hub, at the core of the disruption, while unconnected applications remained operational.

Reports of the outage began climbing at around 1725 GMT on November 12, and Downdetector received reports from users in more than 70 countries and territories. More than 430 million people use Microsoft 365 apps, according to Microsoft's website, and business and government email and collaboration were widely disrupted over the two days, including municipal email in Southern California cities such as Rancho Palos Verdes and Barstow, which later recovered. Microsoft had said on November 13 that there was no timetable yet for full restoration; the November 14 announcement closes the incident, with only the full post-incident report still to come.
