Microsoft 365 services, including Outlook, Defender, Purview, and Teams, were down on Thursday. Downdetector, a platform that tracks online outages, showed at least 10,000 reports at the time of writing this story. While Downdetector showed that Amazon Web Services (AWS), its server status page shows no issues.

In a brief statement, Microsoft confirmed the outage. “We're investigating a potential issue impacting multiple Microsoft 365 services, including Outlook, Microsoft Defender and Microsoft Purview. Further information can be found in the admin center under MO1221364,” it said on X, platform formerly known as Twitter.
When will Outlook, Teams, Purview, Defender be back?
Microsoft has not provided a specific Estimated Time of Resolution (ETR) yet. The status remains listed as “Investigating” in Microsoft’s admin center and service dashboards, meaning engineers are still diagnosing and resolving the root cause. Historically, similar outages took several hours to resolve once mitigation actions were applied fully.
Tips while the outage continues
Check the Microsoft 365 Admin Center status (Service Health) if you’re an admin; updates are frequently posted there. Try accessing services later if you see errors; partial service restoration often occurs before full resolution. Be prepared for intermittent connectivity until Microsoft reports a full fix.
