I need help adding a brand-new feature to an existing Outlook add-in that will run primarily in the web version of Outlook. The current codebase is functional, but it lacks the “Outlook Pluggin” capability we have in mind—essentially an extension to the core plug-in that improves the user’s workflow inside the mailbox. I’m looking for someone who already knows the quirks of Office.js, the JavaScript APIs for Outlook on the web, and the deployment process through Microsoft 365 admin center. Here’s what I’m expecting: • You’ll review the present add-in, design the new feature, and integrate it cleanly without breaking existing functionality. • The work must be fully compatible with the web client, tested in modern browsers, and packaged for store or centralised deployment. • Source code, build instructions, and a short setup guide should be delivered so my internal team can maintain it going forward. If you’ve previously shipped Outlook web add-ins and can jump straight into coding, debugging, and optimising, let’s talk.
