Thanks for the CHM, I'll look for it.

My problem is getting stranger. I'll moved my test code from simple MAPI to Outlook automation (I know Outlook uses MAPI). I still get the attachment in the main text body if I send it to my Yahoo e-mail address but if I send it to my other account and use Outlook to read it -- its ok. If I forwarded this 'ok' e-mail back to Yahoo, its wrong (attachment in main body). It must be the way Yahoo reads the attachment.

Thanks again, John
