Microsoft 365 Outage Disrupts Outlook, Teams and Other Services

Microsoft 365 experienced a major service disruption, leaving users facing problems accessing Outlook email, Microsoft Teams and several other cloud-based services. Microsoft is working to restore normal operations by restarting affected servers and reducing network pressure.

According to reports, the disruption affected multiple Microsoft 365 services across parts of the Americas. Microsoft attributed the connectivity problems to several servers becoming unresponsive after failing automated health checks.

Key points:

• Outlook and Exchange Online users experienced access problems.
• Microsoft Teams, SharePoint Online, Microsoft 365 Copilot and Microsoft Defender XDR were also affected.
• Microsoft began shifting network traffic away from affected infrastructure and restarting unresponsive servers.
• Downdetector recorded a sharp rise in user reports before complaints began declining.
• No evidence of a cyberattack was reported as the cause of this incident.

Microsoft has not confirmed the precise underlying cause or when every affected service will be fully restored.
