MAPI send mail missing body

[Andrew Cutforth]

I am using simple MAPI to send mail. My program was working just fine on
earlier versions of Outlook but now I am using Outlook XP on Windows XP and
I have a problem:

I send the mail non-interactively and it appears in my outbox. The message
in the outbox is complete and correct. I tell outlook to send/receive and
the mail is sent but when it gets to the other end the body text is missing.
In my sent box the message is still complete.

If I send the mail interactivly so the send mail dialog window is shown and
press the send button on there the body text does not go missing.

This is very strange, can anyone help ?

Thanks
