Microsoft executive vice president Charles Lamanna apologized on November 13, 2026, for a disruption affecting Outlook, Exchange Online and other Microsoft 365 services. In a post on X, he said the team was working to resolve the issue and would provide further updates.
The disruption initially affected Teams. Microsoft later confirmed that Exchange Online and Outlook were also affected. Some Exchange-dependent features in Teams, SharePoint Online and Microsoft 365 Copilot were disrupted as well.
At the time of IT Home’s report, the services had not fully recovered. Microsoft said some earlier fixes had not worked as expected and that it was exploring other recovery options. It had not given a timetable for full restoration.
Lamanna said there was no indication that the incident was linked to malicious activity or a cyberattack.
