Microsoft 365 Add-in developemt Checklist for Business Teams
A checklist for preparing an Office add-in for tenant testing, manifest review, Admin Center deployment, and production handoff.
Deployment is more than uploading a manifest
A production-ready Office add-in needs a stable manifest, secure hosting, tested permissions, predictable authentication, and a rollout plan that IT teams can review.
The goal is to avoid surprises after the add-in reaches real users. Testing should happen with the same Microsoft 365 environment, user roles, and data access patterns expected in production.
Pre-deployment checklist
Before rollout, review the add-in from both user and admin perspectives.
- Validate manifest URLs, icons, permissions, app domains, support links, and version metadata.
- Test sign-in, token renewal, error states, and permission consent with realistic tenant accounts.
- Confirm HTTPS hosting, environment variables, API keys, CORS rules, and backend monitoring.
- Run cross-platform checks in the Office clients your team actually uses.
- Prepare a short admin handoff with deployment steps, support contact, known limitations, and rollback notes.
A smoother rollout path
For business teams, the safest path is usually pilot deployment first. Give access to a small group, collect feedback, fix workflow friction, then expand to the wider tenant.
