you can use .SenderEmailAddress if you are using outlook 2013 library.

@ yo_bee MailItem.SenderEmailAddress is read-only not tochange the sender

I cannot say for current versions of Outlook, but way back in 2003, we found out, as you seem to have done, that there was no way to change the sender with Outlook.

We found a low cost SMTP server at www.componentsource.com that was even easier to use than Outlook from VBA code, and that had all the features we wanted. My customer used it for years without any problem.
