>I am using the MapiMail class to send email from a VFP 6 program. It works fine on my development computer but when I try to send mail on another computer, it is unable to create the MAPI session. I have successfully registered MSMAPI32.OCX on all machines and as far as I can see there is no difference in the setup of Outlook and Outlook Express on the computers.
