Microsoft 365 outage drags into Friday, hitting Copilot and AI connectors

What Microsoft reported

Microsoft 365 users were still reporting service interruptions on the morning of Friday 13 November. At 2:14 UTC that day, Microsoft's service health dashboard continued to list degraded service for enterprise and consumer products, according to Cryptopolitan.

The problems were not confined to Outlook. Microsoft 365 Copilot and the Microsoft connectors used in systems such as ChatGPT and Claude were also affected, the report said.

How the outage spread

Outlook users began complaining about losing their connections shortly before 13:00 Eastern on Thursday 12 November. Later Microsoft updates indicated that many of the affected services depended on Exchange Online.

That dependency explains the uneven pattern users saw: Teams chats and online meetings kept working, but scheduling meetings did not work properly. Files stored in SharePoint remained available.

Other Microsoft tools that rely on email and calendar data were hit as well. Copilot Chat could fail to load or respond, and Microsoft Graph requests could time out. Microsoft also warned of delays in email, according to the report.

Open questions

Microsoft had not said by the time of the report what caused the failure or when full service would be restored. The dashboard entry at 2:14 UTC on 13 November showed degradation rather than recovery.
