Darren,
OE doesn't have the same object model that Outlook has. You need to:
oleMAPISession = createobject( "MSMAPI.MAPISession.1" )
There is a full example over on my website under Q&A, General
>Maybe this is a microsoft problem but every time I set Outlook express to by my simple mapi default and then try a createobject("mapi.session") I recieve an ole error. WHen it is not set I do not recieve an error. I am trying to put a message in my outbox of outlook express through vfp. Any thoughts would be great
