C#: Sending email from a specific account when multiple accounts exist in Outlook?

Question

Somehow I accidentally deleted this message trying to edit it... sorry.
Microsoft.Office.Interop.Outlook.Application outApp = null;
outApp = Marshal.GetActiveObject("Outlook.Application") as Microsoft.Office.Interop.Outlook.Application;
MailItem mailItem = (MailItem)outApp.CreateItem(OlItemType.olMailItem);
mailItem.Subject = "Director Script Confirmation Request";
mailItem.To = person;
mailItem.Body = message;
//mailItem.Display(false);
mailItem.Send();
How do I send email from a specific account when multiple accounts exist in Outlook?
Below is the code that I have. I think I'm supposed to use the AddressEntry or AddressEntries to designate where emails are sent from. However, at the moment, I haven't found an example.

Hello SV,
The MailItem class provides the
SendUsingAccount property which allows to set an Account object
that represents the account under which the MailItem is
to be sent. Here is what MSDN states:
The SendUsingAccount property can be used to specify the account
that should be used to send the MailItem when the Send method
is called.
Sub SendUsingAccount()
Dim oAccount As Outlook.account
For Each oAccount In Application.Session.Accounts
If oAccount.AccountType = olPop3 Then
Dim oMail As Outlook.MailItem
Set oMail = Application.CreateItem(olMailItem)
oMail.Subject = "Sent using POP3 Account"
oMail.Recipients.Add ("[email protected]")
oMail.Recipients.ResolveAll
oMail.SendUsingAccount = oAccount
oMail.Send
End If
Next
End Sub
