Summary
Insurance agents spend much of their day in Outlook while client, policy, and servicing work must be captured accurately in core insurance systems. A legacy COM-based Outlook add-in had become increasingly difficult to support as the Microsoft 365 ecosystem shifted toward modern, web-ready add-in standards. Sonata Software helped the client modernize this critical workflow with a React-based Outlook add-in that reduces manual effort, supports seamless tagging of emails and attachments to the right business context, and infuses AI-assisted summarization into agent documentation. The result is a more productive, manageable, and future-ready inbox experience for high-volume insurance teams.

Pressure points
The client needed to retire a legacy COM-based Outlook add-in and move to a modern Microsoft 365 add-in model. The existing approach created technology, deployment, and user-experience constraints: desktop dependency, heavier release management, inconsistent cross-platform behavior, and limited flexibility for AI-enabled workflow enhancements. At the same time, agents needed a faster way to capture email-based servicing work without misfiling, missing tags, or duplicating documentation effort.
Key challenges:
- Technology obsolescence: The COM-based add-in model had become harder to sustain as Microsoft 365 advanced toward modern, web-enabled extensibility.
- Microsoft 365 platform shift: The client needed to leverage the new Outlook add-in platform to support a consistent experience across desktop and web users.
- Manageability and deployment friction: Legacy plug-in management increased administrative effort for upgrades, compatibility testing, governance, and support.
- Manual filing and tagging risk: Agents spent time downloading, uploading, classifying, and tagging communication, increasing the chance of errors and rework.
- AI-readiness gap: The legacy foundation limited the ability to embed AI assistance into documentation, summarization, and workflow guidance.
Solution highlights
Sonata Software engineered a modern Outlook add-in using React and Microsoft 365 add-in capabilities, transforming the inbox into a connected workspace for insurance agents. The solution helps agents file and tag emails and attachments to the right client, policy, or service context with fewer steps; use AI-assisted summaries to accelerate activity documentation; and work within a more secure, manageable, and scalable architecture. Sonata combined product engineering, user experience design, API integration, Microsoft ecosystem expertise, AI enablement, DevSecOps, quality engineering, and release governance to deliver a modernization program designed for enterprise adoption.
