Navision Application Server & MSMapi problem

Hi,

I do have a problem with nas & msmapi.

When i run a codeunit in foreground from a navision client which has to send an email using msmapi the email is being succesful send.

When i run this same codeunit in a nas with the same (Windows)user on the same machine the mail is not send.

Here is my code :

MAPISession.DownLoadMail := FALSE; 
IF MAPISession.SessionID = 0 THEN BEGIN 
  IF NOT GUIALLOWED THEN BEGIN 
    IF "E-Mail Profile Name" = '' THEN BEGIN 
      recKTNNASApplication.RESET; 
      recKTNNASApplication.SETCURRENTKEYCode,Application,Company); 
      recKTNNASApplication.SETRANGE(Code,'BACKGROUND'); 
      recKTNNASApplication.SETRANGE(Application,'KTN'); 
      recKTNNASApplication.SETRANGE(Company,COMPANYNAME); 
      IF recKTNNASApplication.FIND('-') THEN 
       "E-Mail Profile Name" := recKTNNASApplication."E-Mail profile name"; 
    END; 
    MAPISession.UserName := "E-Mail Profile Name"; 
    MAPISession.LogonUI := FALSE; 
  END; 
  MAPISession.SignOn; 
END;

MAPIMessages.SessionID := MAPISession.SessionID; 
MAPIMessages.Compose; 
fct_SetNames(1,ToName); 
MESSAGE('set names'); 
fct_SetNames(2,CCName); 
MESSAGE('set names2'); 
MAPIMessages.MsgSubject := Subject; 
MESSAGE('set subject'); 
NoOfAttachments := 0; 
WHILE AttachFileName[NoOfAttachments + 1] <> '' DO 
NoOfAttachments := NoOfAttachments + 1;

IF NoOfAttachments = 0 THEN BEGIN 
  MAPIMessages.MsgNoteText := Body; 
  MESSAGE('body'); 
END ELSE BEGIN 
  MESSAGE('%1',NoOfAttachments); 
  MESSAGE('%1',AttachFileName[1]); 
  MAPIMessages.MsgNoteText := Body + PADSTR('',NoOfAttachments); // reserve positions for multiple attachments 
  FOR i := 1 TO NoOfAttachments DO BEGIN 
    MAPIMessages.AttachmentIndex := i - 1; 
    MAPIMessages.AttachmentType := 0; 
    MAPIMessages.AttachmentPathName := AttachFileName[i]; 
    MAPIMessages.AttachmentPosition(STRLEN(Body) + i - 1); 
  END; 
END;

MESSAGE('before sending'); 
MAPIMessages.Action(3); // Send or //MAPIMessages.Send; 
MESSAGE('after sending');

When i go and look in the event log the last message is "before sending" and the nas is hanging and doing nothing ....

First i assumed it has something to do with profiles but i checked this. I also tryed this with the outlook app open and closed!

Anyone ????
