Upgrade Microsoft 365 Authentication in Einstein Activity Capture to Microsoft Graph
Microsoft retires Exchange Web Services (EWS) for Microsoft Office 365 in October 2026, after which Einstein Activity Capture configurations on EWS stop syncing. Use the single-click upgrade tool to move to Microsoft Graph authentication; new EAC + Microsoft 365 setups from Spring '26 already use Microsoft Graph. If EAC uses User-Level OAuth, users must reconnect their accounts.
