Why it matters: Retirement / removal — plan migration

Access to Archive mailboxes (Main + Auxiliary) through Microsoft Graph. The goal is to give users a single, seamless Archive view, even though Archive data may physically reside across multiple auxiliary mailboxes with EWS Graph APIs getting deprecated by OCT 2026.
