Microsoft 365 outage drags into Friday, hitting Copilot and AI connectors
Microsoft's service health dashboard still reported degraded enterprise and consumer products at 2:14 UTC on 13 November, after Outlook problems began the day
Key takeaways
- Microsoft's service health dashboard reported degraded service for enterprise and consumer products at 2:14 UTC on 13 November.
- Outlook users began reporting lost connections shortly before 13:00 Eastern on 12 November.
- Microsoft said many affected services depended on Exchange Online, which explains why Teams chats kept working while scheduling did not.
- Microsoft 365 Copilot and Microsoft connectors used in systems such as ChatGPT and Claude were also affected.
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.
