Could you build this?
Partial While the signature design tool is simple, building an enterprise-grade Microsoft 365 add-in with silent Entra ID authentication and centralized tenant deployment requires specialized M365 manifest and administrative expertise.
What it would actually take: It requires building an Outlook Web Add-in (Office.js) packaged with single-sign-on (SSO) via Microsoft Entra ID and published through the Microsoft 365 Admin Center for centralized deployment. The hard part is navigating Office.js lifecycle events across native Windows Outlook, Mac Outlook, and web Outlook, ensuring client-side signature injection works without latency or breaking email formatting across diverse Outlook rendering engines.
