How to Start MAPI Session?

We have a Delphi application that successfully generates and sends a
Microsoft Mail message, provided that a MAPI messaging session is already
started.

If a session is not started, the email generation fails, and an error is
returned stating that no current session exists.

How can I start a MAPI messaging session programmatically? We don't want to
require that our users start Outlook before using the program.

Thanks in advance-
Alan

You can start a Simple MAPI session using MAPILogon.

As Yorai Amino says, you can start a Simple MAPI session with MAPILogon.
I would suggest that you consider trying first to log to any existing
session, then if that fails try to log on to a new session.
You can also use MAPISendMail, make sure you find the help reference
with the C declaration, which is also Simple MAPI. In all cases there is
the option of having a user interface displayed if required to prompt
for things like the Profile Name.

Could you please provide an *example* of MAPILogon, including the
declarations for any variables passed to the function (like the lplhSession
parameter).

Whenever I call it, I get a return code of 2.

Thanks,
Alan

procedure TForm1.Button1Click(Sender: TObject);
var
Session: THandle;
begin
MAPILogon(Application.Handle, nil, nil, MAPI_LOGON_UI, 0, @Session);
MAPILogoff(Session, 0, 0, 0);
end;

Thank you, Yorai. It works perfectly.
