I found that the out of box button [Export to Excel] is invisible for certain entity like lead, opportunity but visible for activity entity. Have checked the entity ribbon definition using command checker, seems there is a <HideCustomAction> on this button(homegrid.{entityname}.ExportToExcel), and <HideCustomAction> is applicable from a managed solution by other provider. Currently we can not find the original managed solution
in this case, is it possible to /restore/ the visibility of the export button? Thanks
