# Salesforce Inbox

Check out the latest improvements to Salesforce Inbox.

- **[Upgrade Microsoft 365 Authentication in Inbox to Microsoft Graph](https://help.salesforce.com/s/articleView?id=release-notes.rn_sales_productivity_inbox_graph_migration.htm&release=264.0.0&type=5)**  
    Transition your Inbox’s Microsoft 365 authentication method from Exchange Web Services (EWS) to Microsoft Graph, which is more modern, secure, and scalable. Microsoft is retiring EWS in October 2026, so switch to Microsoft Graph to avoid service disruption.
