a large Microsoft 365 outage impacted key cloud services including SharePoint Online, Teams, OneDrive, Power BI, Power Automate, Power Apps, Copilot Chat, Copilot Studio, and the Microsoft 365 Admin Center; Microsoft has attributed this to a maintenance-related network routing bug and confirmed full-service restoration after rolling back the change. At the same time, organizations face a July 2026 deadline for the complete retirement of classic SharePoint Alerts, requiring manual migration to SharePoint Rules or Power Automate flows. Microsoft is also advancing its AI and automation strategy: the 2026 Power Platform release wave 1 is delivering new AI agent authoring and Copilot-powered actions in Power Automate, modernized experiences and AI features in Power Apps, and deeper Fabric/Power BI integration. Copilot Studio is evolving with new agent experiences and guidance hub capabilities, and Microsoft’s expanded partnership with Mistral is bringing additional frontier AI models into Copilot Studio and other enterprise offerings, further embedding AI into Microsoft 365 and Power Platform solutions.
- Major outage: On July 23, Microsoft 365 experienced a significant outage affecting Teams, SharePoint Online, OneDrive, the Admin Center, Copilot Chat and other services; Microsoft has traced the root cause to a bug in automated network maintenance that removed IP routes from more devices than intended, and has now confirmed recovery.
- Service impact: SharePoint Online and Teams saw the bulk of user complaints, with errors, slow loading, and intermittent access reported across collaboration and admin experiences.
- Regional scope: The disruption primarily affected customers whose Microsoft 365 traffic traversed North America / West US Azure-region infrastructure, but had knock-on effects across multiple workloads.
Power Platform (Power Automate, Power Apps, Power BI, Power Pages)
- 2026 release wave 1: Microsoft has published its Power Platform 2026 release wave 1 plan, detailing new features shipping April–September 2026 across Power Apps, Power Automate, Power BI and related services.
- Power Apps: Updates include a refreshed model-driven UI, improved mobile and offline capabilities, enhanced search, and expanded AI features to support more intelligent, modern app experiences.
- Power Automate: New capabilities focus on AI agent authoring and optimization, self-healing for desktop flows, Copilot Studio–powered actions in cloud flows, and consolidated governance and reporting for admins.
- Power BI: Fabric and Power BI are noted among services impacted by the recent outage, reinforcing the importance of resilience in analytics workloads built on Microsoft’s cloud data stack.bleepingcomputer+1
- Power Pages: While not specifically called out in the outage documentation, Power Pages continues to be covered under the broader Power Platform release wave plans and governance guidance.
SharePoint Online and Power Automate (alerts retirement)
- SharePoint Alerts retirement: Microsoft’s multi-step retirement of traditional SharePoint Alerts reaches its final phase in July 2026; all remaining alert functionality will be turned off and cannot be extended.
- No automatic migration: There is no automatic migration path; organizations must manually rebuild each alert as either a SharePoint Rule or a Power Automate flow.
- Governance implications: Since January 2026, creation of new Alerts has been disabled and existing alerts have been forced to expire regularly, driving admins toward Power Automate-based patterns for notifications and monitoring.
Copilot Chat, Copilot Studio, AI strategy
- Copilot Studio evolution: Recent updates introduce a new agent-building experience in Copilot Studio and expanded guidance hub content, including Agent Debugger, Agent Library, Agent Insights Hub, Power Shield, and Agent Review Pipeline, aimed at more robust AI agent lifecycle management.
- Copilot Chat in outages: Copilot Chat was among the services disrupted during the July 23–24 incident, with users experiencing delays or failures in actions and queries, highlighting AI features’ dependence on core Microsoft 365 connectivity.
- Expanded Mistral partnership: Microsoft and Mistral have announced a deeper strategic partnership, bringing models like Mistral Medium 3.5 and OCR 4 into Microsoft Foundry and Copilot Studio, giving enterprises more AI model choice and control—especially for regulated industries.
