This paper explores the methodologies for deploying Yahoo Mail services on the Windows 11 operating system.

This document analyzes three primary deployment vectors: the deprecated legacy client, the modern PWA implementation via Microsoft Edge, and the integration of native system protocols (IMAP/SMTP).
