This policy setting allows you to prevent the organization name from being displayed in the buttons in the Excel ribbon used to create PivotTables from Power BI datasets. By default, the organization name will be shown in the ribbon if it is available from Graph. If you enable this policy setting, the organization name will not be shown. If you disable or don’t configure this policy setting, the organization name will be shown. Note: This policy setting only applies to subscription versions of Office, such as Microsoft 365 Apps for enterprise.
