Microsoft Says Outlook, Teams and Copilot Services Are Fully Restored

Microsoft said its services had returned to normal after an outage disrupted Outlook, Teams and Copilot and interrupted work for traders, government offices and businesses worldwide.

Microsoft's status page listed its products as operating normally. The company also said delayed Microsoft 365 email had finished processing, clearing the backlog. The affected products included Outlook, Teams and Copilot, Microsoft's artificial intelligence tool.

The outage began around noon ET on Nov. 12. Reports of disruption spanned 74 countries and territories within about an hour as Microsoft worked to restore Outlook, Teams and Copilot. Mailbox access could fail and email delivery was delayed. Teams chats and online meetings largely continued to work, while calendar features that relied on email could fail.

During the disruption, users also reported missing meeting invitations and unresponsive web pages. The restoration closes an outage that interrupted work across multiple regions.
