Microsoft Purview: Data Lifecycle Management-Graph API Support for Archive Mailboxes
Archive mailboxes (including auxiliary mailboxes) will be accessible through Microsoft Graph API, replacing deprecated EWS Graph APIs. Admins should plan to migrate integrations from EWS to Graph APIs for archive mailbox access.
Action required: Plan migration of archive mailbox integrations from EWS Graph APIs to Microsoft Graph API before EWS deprecation completion.
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 being deprecated.
