Microsoft’s ecosystem in late May 2026 is defined by major AI‑driven enhancements across Power Platform, Copilot Studio, and Microsoft 365, with a strong emphasis on agentic workflows, governance, automation intelligence, and modernized app experiences. Power Apps introduces general availability of Power Fx User‑Defined Types, Power Automate expands AI‑agent‑powered automation and process intelligence, and Copilot Studio deepens its role as the orchestration layer for agentic apps. Microsoft 365 continues to roll out roadmap updates across SharePoint, OneDrive, Outlook, and Teams, with Copilot integration as the unifying theme.

1. Power Apps: User‑Defined Types (UDTs) Now Generally Available

• Power Apps has released Power Fx User‑Defined Types (UDTs) to general availability, enabling makers to define strongly typed structures for complex data and JSON parsing.
• This significantly improves data validation, custom function design, and type‑safe app development.
  

2. Power Apps: Custom Tools & Rich UI for Copilot‑Integrated App Conversations (Public Preview)

• Makers can now build custom MCP‑powered tools and Fluent‑based UI widgets that integrate directly into Copilot‑driven app experiences.
• This expands Copilot from simple Q&A to contextual, visual, action‑oriented workflows inside model‑driven apps.
  

3. Power Automate: AI‑Driven Automation & Process Intelligence (2026 Release Wave 1)

Key highlights from the April–September 2026 release wave:

• AI agents bring self‑healing and intelligent adaptation to desktop flows.
• Copilot Studio‑powered actions allow cloud flows to orchestrate AI agents and call desktop flows.
• Object‑centric process mining becomes generally available, with deep Microsoft Fabric integration.
• Enhanced governance, version control, collaboration, and centralized credential management for makers.
  

4. Power Pages: AI‑Enhanced Portal Development & Security Improvements

• Power Pages continues to expand AI‑assisted development and introduces enhanced security agent features for low‑code and pro‑dev scenarios.
• Better integration with AI tools supports building intelligent business portals for employees, customers, and partners.
  

5. Copilot Studio: Expanded Agentic Workflows & Architecture Updates

Recent updates from the Architecture Center:

• New reference architectures for automating service order lifecycles, SLA governance, and Dataverse Git‑based deployments.
• Copilot Studio continues to evolve as the central orchestration layer for agentic workflows across Power Platform.

6. Power Platform 2026 Release Wave 1: Broad AI & Modernization Push

Across Power Apps, Power Automate, Power Pages, and Copilot Studio:

• Modernized UI, improved mobile/offline capabilities, and generative page creation.
• AI‑powered automation, agent authoring, and governance improvements.
• Expanded Dataverse integration and standardized theming.

7. Microsoft 365 & Office 365: Roadmap Updates for May 2026

• Microsoft 365 continues to ship updates across SharePoint, OneDrive, Outlook, Exchange, Teams, and Purview, with Copilot integration as a central theme.
• May 2026 is described as “one of the most significant Copilot months,” with major admin‑impacting changes.

(Note: The roadmap article referenced does not list item‑level details in the snippet, but confirms broad updates across core Microsoft 365 workloads.)

8. SharePoint Online: Integration Improvements via Power Platform

While no standalone SharePoint‑specific May 2026 news surfaced in search, SharePoint appears in:

• Power Automate reference architectures (e.g., uploading files with metadata from model‑driven apps).
• Enhanced integration patterns across Power Platform and Copilot workflows.
