Note We’re reorganizing the Einstein Activity Capture documentation. We’re moving some information around, but we aren’t deleting anything.

Important In February 2025, Microsoft retired the ApplicationImpersonation role in Exchange Online. As a result, Salesforce is retiring service account OAuth 2.0 access to Microsoft Office 365. To continue activity data capture, upgrade to org-level OAuth 2.0 authentication in Einstein Activity Capture settings. During the upgrade process, you're prompted to log in to your Office 365 tenant. Make sure that you log in to the same tenant you used when creating the connection. If you don't, reset your Einstein Activity Capture connection and start over. See [Einstein Activity Capture to MS Office 365: Service Account OAuth 2.0 Retirement](https://help.salesforce.com/s/articleView?id=002420794&type=1&language=en_US).
