        Outlook.MailItem mailItem = Item as Outlook.MailItem;
        if (mailItem != null)
        {
           MessageBox.Show("Sender's Email Address "+mailItem.SenderEmailAddress);
           MessageBox.Show("Sender's Email Address "+mailItem.SentOnBehalfOfName);

Please can you anyone help me out I want to get From, SentOnBehalfOfName and Account name from with the email was sent.

Answer 1

Sender related properties are set only after the message is actually sent and moved to the Sent Items folder. You might want to use the Items.ItemAdd event on the Sent Items folder.

Answer 2

This is the Code i have used

    public Outlook.MAPIFolder sentFolder = null;
    public Outlook.Items itmsSentFolder = null;
    sentFolder = applicationObject.Session.GetDefaultFolder(Outlook.OlDefaultFolders.olFolderSentMail);
    itmsSentFolder = sentFolder.Items;
    itmsSentFolder.ItemAdd += new Outlook.ItemsEvents_ItemAddEventHandler(itmsSentFolder_ItemAdd); 
void itmsSentFolder_ItemAdd(object Item)
        {

                if (Item is Outlook.MailItem)
                {
                    Outlook.MailItem mailItem = Item as Outlook.MailItem;
                    if (mailItem != null)
                    {
                        MessageBox.Show("Sender's Email Address " + mailItem.SenderEmailAddress);
                        MessageBox.Show("Sent On Behalf Of Name " + mailItem.SentOnBehalfOfName);
                        Outlook.Account ac = (Outlook.Account)mailItem.SendUsingAccount;
                        if(ac != null)
                        {
                            MessageBox.Show("Sender's Account Name " + ac.SmtpAddress);
                        }

                    }

            }
        }

Thanks for the idea Dmitry Streblechenko
