How can I send an email using a distro/group email address?

My code is getting the email address of the user that is currently login on the computer.

What I have tried:

C#

Application oApp = new Application();

        MailItem oMailItem = (MailItem)oApp.CreateItem(OlItemType.olMailItem);
        oMailItem.Recipients.Add(toTxtBox.Text);
        oMailItem.CC = ccTxtBox.Text;
        oMailItem.Subject = sbjTxtBox.Text;

        string x ="";

        string date = Session["date"].ToString();
        string to = Session["to"].ToString();
        string subject = Session["subject"].ToString();             

        oMailItem.HTMLBody = bodyTxtBox.Text + getEmailFile(x);

        if (FileUpload1.HasFile)
        {
            int AttachType = (int)OlAttachmentType.olByValue;
            Attachment Attach = oMailItem.Attachments.Add(FileUpload1.PostedFile.FileName, AttachType, Type.Missing, Type.Missing);
        }

        ((Microsoft.Office.Interop.Outlook._MailItem)oMailItem).Send();

Assuming that internal relaying is allowed by your Email server then;

Are you trying to send on behalf of a group email address?
If so the User account that is running the code will need Send As permissions.
If you are trying to send to a Distribution Group then the User account running the code should send to the Group Email address.
If the Distribution Group is an Outlook group (Contact Group versus Exchange Distribution Group) then the User running the code will need the group defined within their Outlook profile

toTxtBox.Text are add in multiple email id in ";" separated

used following code

string[] addresses = toAddress.Split(";");
foreach (string address in addresses) {
if (!string.IsNullOrEmpty(address)) {
objMessage.To.Add(new MailAddress(address));
}
}

smtp.Send(objMessage);
