# Upgrade Microsoft 365 Authentication in Einstein Activity Capture to Microsoft Graph

Transition your Einstein Activity Capture’s Microsoft 365 authentication 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. Proactive notifications and a single-click tool make the migration process smooth.

**Where:** This feature is available in Lightning Experience in Starter, Professional, Enterprise, Unlimited, Einstein 1 Sales, and Agentforce 1 Sales editions. It’s also available with the Einstein for Sales, Sales Engagement, and Revenue Intelligence add-ons.

**When:** This feature is available starting in February 2026.

**Who:** The update is available if Einstein Activity Capture is configured to use Microsoft 365. If you’re setting up Einstein Activity Capture with Microsoft 365 starting in Spring ’26, you’re automatically authenticated by using Microsoft Graph.

**Why:** This migration is essential to align with Microsoft’s evolving security standards and to avoid potential disruptions as EWS reaches its end of life in October 2026. By transitioning to Microsoft Graph, Salesforce makes sure that your organization remains compliant and competitive, with improved support for modern features and enhanced user-level authentication.

**How:** Before and during migration, make sure that your Azure admin has granted Microsoft Graph consent. Then, use the upgrade tool to complete the upgrade.

If Einstein Activity Capture is configured to use User-Level OAuth, users must reconnect to their Microsoft 365 accounts to complete the connection migration.
