Short answer
Microsoft is retiring Exchange Web Services in Exchange Online, so Salesforce email and calendar integrations that rely on EWS must move to Microsoft Graph-based options such as Einstein Activity Capture and the current Outlook integration.
Why firms make this move
Several older Salesforce email features and third-party sync tools connect to Exchange Online through EWS. Once Microsoft turns EWS off, those connections stop syncing email and calendar. Firms need to find what still uses EWS, move to supported Graph-based features, and confirm compliance archiving still captures what it should.
What moves
- Email and calendar sync configuration
- Outlook integration and add-in settings
- Third-party sync tools that use EWS
- Admin consent for Microsoft Graph
How the data maps
| From | To |
|---|---|
| EWS-based sync | Einstein Activity Capture or Outlook integration on Microsoft Graph |
| Lightning Sync | Einstein Activity Capture |
| Third-party EWS tool | Vendor's Graph-based version or replacement |
What to watch out for
- Tools nobody knew used EWS
- Microsoft Entra admin consent
- Reporting differences with Einstein Activity Capture
- Archiving coverage
How Vantage Point runs the migration
- Inventory email and calendar integrations
- Grant Microsoft Graph consent
- Configure Einstein Activity Capture and the Outlook integration
- Pilot and verify reporting
- Retire EWS connections
Typical timeline
Typically 2 to 4 weeks.
