I'm attempting to use the following code to send an email using OUTLOOK from Word. The code runs without error, but the e-mail is apparently not sent (not received on other end).

If if remove this line:
oMailItem.DeleteAfterSubmit = True

The mail is sent (received) but remains in the sent items folder.

How can I send an email and then immediately remove it from the sent items folder.
