I think for that to work, you'll have to handle it on an Exchange server. I don't think you can do that from Access sending email via Outlook only... there should be some method on the Exchange server directly to handle such needs. I know our company has some email addresses setup that way where I work, but I don't think it's done directly through the Outlook desktop application. Unfortunately, I've not had any need, myself, to dig in and find out the how/what/why of it all.
