Microsoft Outlook 全球宕机，M365 用户与员工均无法收发邮件
微软 Outlook 全球挂了，连自家员工都发不出邮件，Gary Marcus 也下场评论。用 M365 办公的朋友可以先检查自己邮箱状态，顺手想想企业沟通有没有备用方案。
Microsoft 发生大规模服务中断，Outlook.com 全球范围内宕机，使用 M365 的企业用户同样无法正常使用邮箱服务。Gergely Orosz 在社交媒体上指出，连 Microsoft 自己的员工也无法收发邮件，影响范围覆盖公司内外。由于电子邮件仍是企业沟通的核心工具，此次宕机对依赖 M365 的组织造成了直接的业务中断。
Gary Marcus 转发并评论称这次故障"很有 2026 年的味道"，暗示类似的集中式服务单点故障今后可能更频繁地出现。事件的具体根因尚未公布，官方事故复盘（postmortem）尚未发布，故障持续时间与受影响用户规模均待 Microsoft 后续通报。对依赖单一云厂商套件的企业而言，这次事件再次暴露了 SaaS 邮件服务停摆时的沟通备份问题。
