Why don't my custom fields appear in the add-in?

The Microsoft 365 Outlook add-in in the classic Sales user experience gets data from the Sales application through a REST API call. If the custom fields you created aren't included in the REST service Include in Service Payload, your users can't find those fields in the add-in.

To add the fields to the service payload, go to Application Composer in the sales application and open your custom field record. Select the Include in Service Payload check box and save your changes.

Note: Oracle recommends that you use the Redwood User Experience version of the Microsoft Outlook add in. To get started, see Overview of Microsoft 365 for Redwood UX in the solution playbook, How do I implement Microsoft 365 for Oracle Sales Redwood UX?.
