Sending mail with Outlook.Application C#

Question

I'm trying to send mail from my c#.net application, I've used this code:

var mailItem = (Outlook.MailItem)oApp.CreateItem(Outlook.OlItemType.olMailItem);
    mailItem.Subject = "Error Report from user: " + AuthenticationManager.LoggedInUserName;
    mailItem.HTMLBody = "Test email\n"+ReadSignature();
    mailItem.To = "test@test.com";
    mailItem.Display(true);

The mail doesn't get sent, but added to the outbox folder. I suspect that the mail isn't sent because outlook isn't started. So I googled and came up with this:

        var oApp = new Outlook.Application();

        Microsoft.Office.Interop.Outlook.NameSpace ns = oApp.GetNamespace("MAPI");
        var f = ns.GetDefaultFolder(Outlook.OlDefaultFolders.olFolderInbox);

        Thread.Sleep(5000); // a bit of startup grace time.

        var mailItem = (Outlook.MailItem)oApp.CreateItem(Outlook.OlItemType.olMailItem);
        mailItem.Subject = "Error Report from user: " + AuthenticationManager.LoggedInUserName;
        mailItem.HTMLBody = "Test email\n"+ReadSignature();
        mailItem.To = "test@test.com";

        mailItem.Display(true);

But once again it end up in the outbox folder. I need to start outlook, because I can't specify the FromMail property in every single client application.config. Any ideas?

if you are using web application then you can configure from mail in web.config file — user1102001, Sep 30 '13 at 10:00
Do you really need this overkill to simply send simple email? there are classes that allow sending mail directly without outlook. — Rafal, Sep 30 '13 at 10:02

You need to call the MailItem.Send method:

mailItem.Send();

Doesn't work, the mail still gets inn my outbox folder in outlook. – Tobias Moe Thorstensen Sep 30 '13 at 10:35
@TobiasMoeThorstensen May be allowed inbox size is reached. if then email will go to outbox until enough space is available, did you check that ? – Kurubaran Sep 30 '13 at 11:03
@AccessDenied No. But I fixed it by starting the outlook process and then open the create mail dialog. – Tobias Moe Thorstensen Sep 30 '13 at 11:04

@TobiasMoeThorstensen great! – Kurubaran Sep 30 '13 at 11:07
Try to use Namespace.SyncObjects collection or Namespace.SendAndReceive method to start a sync. Note that message submission is an asynchronous process, so you will need to keep a reference to the Namespace object and the SyncObject (if you are using it) until the message is actually sent. – Dmitry Streblechenko Sep 30 '13 at 14:47
