Designing React portals for Microsoft 365 workflows

Not every enterprise workflow fits neatly into an out-of-the-box portal. React gives teams more control over interaction design, performance, integration patterns, and component reuse when the workflow demands a tailored user experience.

Use custom UI where the user journey needs it

A React portal can sit alongside Microsoft 365, SharePoint, Power Platform, and Azure services when users need richer forms, guided workflows, dashboards, or integration with systems beyond standard connectors.

• Preserve Entra ID and role-based access
• Use SharePoint and Dataverse where they fit the data model
• Prefer reusable components for repeated workflow patterns
