c# - Detect when "Office.Interop.Outlook" don't send mail -

i have c# procedure send mails. procedure call mailitem.send() without error outlook don't send mail, , mail isn't create in outlook "to send" folder.

how detect ?

the code follow:

private void sendmail(string mail, string description) {      registrykey key = registry.classesroot;     registrykey subkey = key.opensubkey("outlook.application");      if (subkey != null)     {           if ((process.getprocessesbyname("outlook").length == 0) && (process.getprocessesbyname("outlook.exe").length == 0))         {             system.diagnostics.process.start("outlook");         }           microsoft.office.interop.outlook.application app = new microsoft.office.interop.outlook.application();         microsoft.office.interop.outlook.mailitem mailitem = app.createitem(microsoft.office.interop.outlook.olitemtype.olmailitem);         mailitem.subject = "release notice";         mailitem.to = mail;          string bodymessage = description;          mailitem.body = bodymessage;          mailitem.display(false);         mailitem.send();      }     else     {         messagebox.show("impossible send mails. contact system administrator.", "system info", messageboxbuttons.ok, messageboxicon.error);     } } 

if send() method not sending error or exception quite possible cannot detect if there error/exception(atleast code)

once message moved outlook server out of reach check status. have rely on outlook server send email.
