if (inlineShape.OLEFormat.DisplayAsIcon)
{
try { inlineShape.OLEFormat.Activate(); } catch (Exception ex) { Logger1.Log(ex.Message, ex.StackTrace); continue; }

string excelPath = string.Empty;
if (string.IsNullOrEmpty(inlineShape.OLEFormat.IconLabel))
excelPath = Path.Combine(attachmentSavePath, "MicrosoftExcel.xlsx");
else
excelPath = Path.Combine(attachmentSavePath, inlineShape.OLEFormat.IconLabel);
Microsoft.Office.Interop.Excel.Application excel;
excel = Marshal.GetActiveObject("Excel.Application") as Microsoft.Office.Interop.Excel.Application;
excel.Application.Visible = false;
excel.DisplayAlerts = false;
excel.ActiveWorkbook.SaveAs(excelPath, Microsoft.Office.Interop.Excel.XlFileFormat.xlWorkbookDefault, Type.Missing, Type.Missing, true, false, Microsoft.Office.Interop.Excel.XlSaveAsAccessMode.xlNoChange, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing);
