Microsoft Purview: Data Lifecycle Management - Graph API Support for Archive Mailboxes
IT admins will gain unified access to archive mailboxes (main and auxiliary) through Microsoft Graph, providing a consolidated view of archive data. EWS Graph APIs will be deprecated by October 2026, requiring migration to the new Graph API approach for continued archive mailbox access.
Action required: Plan migration from EWS Graph APIs to the new Microsoft Graph archive mailbox APIs before the October 2026 deprecation deadline.

Microsoft's description
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.
