Looking at the code at http://www.codeproject.com/ce/SMS_CEMPI.asp I can
use MAPI to send a SMS message on a HTC Typhon (Windows Mobile 2003 SE).

However - I really wish to be able to send MMS messages. As the phone
has a MMS client installed I assume I should be able to use it via MAPI
as well.


By selecting the MMS message store rather than the SMS message store and
PR_ADDRTYPE to "MMS", SubmitMessage() doesn't return an error - however
no MMS is sent, nor does a MMS appear in the drafts, send items or
outbox folder


Any ideas as to why this doesn't work?
