Hi all got a very strange problem with MAPI.  I've created a basic wrapper 
for MAPI which looks like this:

int TSystemTools::SendEmail(TMapiMessage *MapiMessage)
{
   int iRtn = -1;
   Cardinal mError;
   try
   {
         mError = MapiSendMail(0, reinterpret_cast<unsigned 
int>(Application->Handle),
                               *MapiMessage, 
MAPI_DIALOG|MAPI_LOGON_UI|MAPI_NEW_SESSION, 0);
   }
   catch(...)
   {
   }
   iRtn = (unsigned __int32)mError;
   return iRtn;
}

Not impressive there.  Now I call this code in the process of the user 
registering / licencing an application from the LicenceDlg.  In one 
application the code executes no problems, in the orther it doesn't the code 
is exactly the same in other (I've cut&pasted to check).  It simply returns 
MAPI_E_FAILURE which doesn't really help be debug the problem.  Calling code 
looks like this:


     AnsiString szBodyText = "Some registration informtion......"
      TMapiMessage MapiMessage;
      Cardinal mError;
      TMapiRecipDesc MapiRecipients[1];
      MapiRecipients[0].ulReserved      = 0;
      MapiRecipients[0].ulRecipClass   = MAPI_TO;
      MapiRecipients[0].lpszName        = "Sales";
      MapiRecipients[0].lpszAddress    = sales@softwareassociates.nu;
      MapiRecipients[0].ulEIDSize        = 0;
      MapiRecipients[0].lpEntryID        = NULL;

      MapiMessage.ulReserved               = 0;
      MapiMessage.lpszSubject               = "Registration request...";
      MapiMessage.lpszNoteText            = szBodyText.c_str();
      MapiMessage.lpszMessageType     = NULL;
      MapiMessage.lpszDateReceived     = NULL;
      MapiMessage.lpszConversationID   = NULL;
      MapiMessage.flFlags                       = 0;
      MapiMessage.lpOriginator              = NULL;
      MapiMessage.nRecipCount            = 1;
      MapiMessage.lpRecips                   = MapiRecipients;
      MapiMessage.nFileCount               = 0;
      MapiMessage.lpFiles                      = NULL;

      int iErr = SystemTools->SendEmail(&MapiMessage);
      switch (iErr)
      {
            // Error messages
      }
   }

Can anyone see anything that I've done wrong.  As I say, I've cut and pasted 
the code identically from one app to the other.  One works, the other 
doesnt.  God forgive me for ever upgrading to Win2003.  Using C++Builder 6 
Ent, all patches, Win2003 all SP, Outlook 2003 :-)
