title: Enable grouping on protected sheet in Excel Online
body: <p>Is there a way to enable grouping/ungrouping on a protected sheet in Excel Online, using the Excel Javascript APIs or otherwise? On Excel desktop the suggested way seems to be using the <a href="https://msdn.microsoft.com/en-us/library/microsoft.office.tools.excel.worksheet.enableoutlining.aspx" rel="nofollow noreferrer" title="EnableOutlining">EnableOutlining</a> property which isn't saved with the worksheet.</p>
  
  <p>The docs for the Javascript API don't have EnableOutlining as one of the properties we can set.</p>
