Latest Message<\/th>\nTitle: Issues accessing or using Microsoft 365 services routed through the North America region. <\/p>\n

User impact: Users may have experienced issues accessing or using Microsoft 365 services routed through the North America region.<\/p>\n

More info: We’ve confirmed that the issue may have affected multiple Microsoft 365 services, including but not limited to:<\/p>\n

-Microsoft OneDrive: Intermittent connection issues.
-SharePoint Online: Intermittent connection issues. Some users were receiving \u201cSomething went wrong\u201d errors.
-Microsoft Teams: Degraded chat functionality, including images not loading. Additionally, real-time voice apps reporting and historical reporting were not functioning as expected.
-Copilot Chat: Intermittent delays using Copilot Chat and failures in query actions.
-Microsoft 365 Admin Center: Latency and intermittent inability to access features
-Power Automate: Automate flows not loading.
-Microsoft Loop: Unable to open or load Loop pages.
-Microsoft Purview: Degraded Purview DLP Agent response time. eDiscovery and Data -Security Investigations failures when submitting new jobs and delays in processing existing jobs. Additionally, admins may have been unable to view their policies or navigate in the Purview portal. Retries may have succeed.
-Fabric\/Power BI: Users in the West US region may have encountered issues accessing Publish to Web reports. Some users in Europe and Asia Pacific regions may also have been intermittently delayed when accessing Fabric artifacts due to service dependencies in West US.
-Power Apps: Users may have experienced some issues accessing the Power Apps Portal and may also have experienced Canvas Apps not loading and data sources failing to connect.
-Copilot Studio: Users may have been unable to load the Copilot Studio Portal and data sources may also have failed to connect.
-Windows 365: Users may have been unable to select a non-English (United States) language for their Cloud PC post provisioning. They could have tried reprovisioning and language selection again and it may have succeeded on the retry.
– Microsoft Defender: Users may have experienced delays receiving responses from Microsoft Defender Experts. Additionally, investigations and workflows handled by Defender Experts may have been delayed. Furthermore, any remediations that fired via Threat Explorer and Advanced Hunting may have failed. Admins may have to re-trigger remediations manually from Threat Explorer and Advanced Hunting.<\/p>\n

Final status: We\u2019ve completed reverting the networking update and confirmed through service telemetry and customer reports that this issue is resolved.<\/p>\n

Scope of impact: Users accessing Microsoft 365 services through affected network paths in the North America region may have been impacted. Users from other regions who were served by this infrastructure may also have experienced impact.<\/p>\n

Start time: Thursday, July 23, 2026, at 2:44 PM UTC<\/p>\n

End time: Thursday, July 23, 2026, at 6:26 PM UTC<\/p>\n

Preliminary root cause: A recent update to a portion of network infrastructure in the US West region introduced a misconfiguration which interrupted the process by which IP ranges connect requests with downstream services, leading to impact.<\/p>\n

Next steps:
-We\u2019re assessing our traffic routing change processes to ensure similar changes don\u2019t introduce future issues.<\/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<\/tbody>\n<\/table><\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"
