Hi, Paul,

I will not know what email service will be used. The email service provider
can be different among the users of that MAPI application. Do you mean that
has to be done in the exchange server?

All I know is that my computers have outlook and use email services from the
DSL service provider. One of my computer has outlook 2000 and the MAPI
application can send emails; another one has outlook 2003 and the
application cannot send emails. Is there any setting in outlook 2003's
advanced options to get it work?

I have an application that uses MAPI to call outlook to send out email to
a
list of recipients that it pulls out from a database. The new outlooks
(since 2002) do not let my application to send out email. How can I set
the
outlook to trust my application to send email and not to pop up a warning
message?
