This case mirrors common issues where configuration and network challenges prevent proper notification subscriptions, affecting accurate data sync.

Einstein Activity Capture Solution

A careful review of the setup and integration details shows that this problem often comes from misconfigurations or permission issues with Office 365. Ensuring that Salesforce can properly communicate with Microsoft systems is key. Following the right troubleshooting steps can help resolve the error. Below are the steps needed to resolve this issue:

1

Review Integration Settings

Double-check that Outlook Integration is enabled properly. Go to Salesforce Setup > Outlook Integration and ensure all settings are correctly configured.

2

Verify Office 365 Connection

Log in to the Office 365 admin panel to confirm that Salesforce has the required permissions. Ensure the notification endpoints are active and not blocked.

3

Reset Einstein Activity Capture

Temporarily disable Einstein Activity Capture, then re-enable it. This can clear temporary glitches. Confirm the event sync option is turned on afterwards.

4

Test and Monitor Sync

After adjustments, test the sync process. Monitor the notifications and check if new events update successfully in Salesforce.

Limitations to Consider

While these steps typically resolve the issue, limitations remain. Changes in Office 365's notification system or network issues may cause recurring problems. Continuous monitoring and occasional resets might be required.
