How to open outlook mail object as a draft email before sending?

Question

void send_reply(Outlook.MailItem item, HashSet<string> names)
    {
        Outlook.MailItem eMail = item.Reply();
        // want to open an email draft box for user to type in the email's content then return to the program here
        eMail.Display();
        foreach (string s in names)
        {
            eMail.To = s;
            //MessageBox.Show("this is the guy we are sending to " + item.To);
            eMail.Importance = Outlook.OlImportance.olImportanceHigh;
            ((Outlook._MailItem)eMail).Send();

        }
    }

Want to send a reply to a given mailitem but only to the email addresses specified in names. Issue I'm having is when I call eMail.Display() it only shows for like half a second at most then the draft auto closes and I send a blank reply email to everyone in names.

Anyone have any suggestions?

Answer 1

The Display() function returns immediately and makes your message to be sent empty.

You can wait by passing true to the function:

//...
  Outlook.MailItem eMail = item.Reply();
  eMail.Display(true); // <-- here
//...

This will make the window Modal and will wait for user to close it.

Maybe you have also to check if the user closed it without a text inside or have the intention to undo the operation...

To do this maybe you can check the message status or register a handler to one (or both) of Close (and Send ) events.
