Outlook Email Management Add-in

I want to extend Outlook with a modern Office JavaScript add-in focused on smarter email management. The add-in should let me act on a message—tag, categorize, or archive it—without leaving the reading pane and, when required, push its content or attachments straight into a SharePoint document library. Authentication and Graph API calls must flow through Azure AD so single sign-on is preserved for Microsoft 365 tenants.

A solid implementation will include:
• the manifest, web assets, and any Azure functions or APIs
• clear setup instructions for tenant-wide or individual deployment
• concise user documentation that shows the add-in in action

Please base your proposal around previous experience building Outlook add-ins, especially any work that involved SharePoint integration or Azure AD authentication. Code quality, reliability across Outlook desktop, Web, and the latest Mac build, and a clean UI aligned with Fluent UI will form the acceptance criteria for the final delivery.
