Latest Message<\/th>\nTitle: Unable to open files in Office for the web or Microsoft Teams<\/p>\n

User impact: Users may have been unable to open files in Office for the web or Microsoft Teams.<\/p>\n

More info: Impacted Office Apps included, but were not limited to:
– Excel
– PowerPoint<\/p>\n

When users opened documents, impacted users were shown the following error message “Office Online services aren’t available right now. We’re working to restore all services as soon as possible. Please check back soon.”<\/p>\n

Final status: We’ve confirmed through customer reports and service telemetry that the impact has been resolved, and the service has remained stable for an extended period of time. As the issue recovered without any specific engineering actions being implemented, engineer teams continue to investigate the underlying root cause so actions can be taken to prevent the issue from reoccurring.<\/p>\n

Scope of impact: This issue could have impacted any user attempting to access Office Apps using Office for the web or Microsoft Teams.<\/p>\n

Start time: Monday, June 1, 2026, at 12:43 PM UTC<\/p>\n

End time: Monday, June 1, 2026, at 2:27 PM UTC<\/p>\n

Root cause: We’re reviewing service telemetry, diagnostics logs and recent changes to isolate the root cause. We’ll provide more details within the Post-Incident Report.<\/p>\n

Next steps:
– We’re continuing to monitor the service and will complete a thorough post-incident review to help prevent similar issues in the future.<\/p>\n

We’ll provide a preliminary Post-Incident Report within two business days and a final Post-Incident Report within five business days.<\/td>\n<\/tr>\n
