In certain cases, the SharePoint Folder Id Field cannot be used. For example, the Task and Event objects behave differently from other objects. These objects cannot specify a Salesforce object in the SharePoint Object settings, and as a result, they cannot use the SharePoint Folder Id Field.

In such cases, you should:

1. Input the API name of the field into the SharePoint Folder Id Field Override.
2. Leave the SharePoint Folder Id Field blank.

NOTES: This field requires the API name of the field. Ex. "sharepoint_folder_id__c" The SharePoint Folder Id Field Override is REQUIRED in the following scenarios: When the related Salesforce object is Task or Event (OR) When the SharePoint Folder Id Field does not have a value

To learn more about the purpose of the SharePoint Folder Id Field and SharePoint Folder Id Field Override, see our article, SharePoint Folder Id Field.

To view or change your SharePoint Folder Id Field Override, go to Salesforce Setup > Custom Code > Custom Metadata Types > click 'Manage Records' next to SharePoint Object Settings and select your object.
