Example usage (paste in iPython notebook cell)

%%iron --interop

excel.Visible, excel.DisplayAlerts = True, False

workbook = excel.Workbooks.Add()
ws = workbook.Worksheets[1]
c = ws.Range('A1')

# emails = outlook.ActiveExplorer().Selection
emails  = outlook.Session.GetDefaultFolder(Outlook.OlDefaultFolders.olFolderInbox).Items

for email in emails:
    try:
        c.value = email.Subject
        c.Offset(0, 1).value = email.ReceivedTime
        c.Offset(0, 2).value = email.SenderName
        c = c.Offset(1, 0)

    except:
        pass
