In Veeam ONE Reporter, it is very simple to delete a custom dashboard. However, when you remove a dashboard, it is not permanently deleted. The dashboard is first archived so that you are able to restore it at a later time. Perform the following steps to learn how to delete dashboards:
Open Veeam ONE Reporter and select the dashboard that you would like to remove from the Dashboards view.
Click on the right corner of the dashboard. Click on Delete.
