Microsoft Purview: Data Lifecycle Management - Graph API Support for Archive Mailboxes
Microsoft Purview Data Lifecycle Management will gain Graph API support for unified access to Archive mailboxes (main and auxiliary). Admins must migrate off deprecated EWS Graph APIs by October 2026 to maintain uninterrupted Archive mailbox management.
Action required: Plan migration from EWS Graph APIs to new Archive mailbox support in Microsoft Graph before October 2026 deprecation.
Key dates
- 2025 — preview (Feature in development)
- 2026-10 — deprecation (EWS Graph APIs deprecated)
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.
