I've been calling the MapiAddress function with the code below,

only the problem is retrieving multiple addresses, i can retrieve one, but i get stuck on making an array of it again..

if anyone can help, please..

function TNovaMapi.AddressList: MapiRecipDesc;
var
 Flags     : Cardinal;
 pmrd      : amrd;
 mrd       : PMapiRecipDesc;
 mrd2      : PMapiRecipDesc;
 t         : cardinal;
 I         : integer;
 Success   : Boolean;
begin
 mrd  := @pmrd;
 mrd2 := @pmrd;
 t := 1;
 Success := False;

 case fNMEditFields of
  ef0: i := 0;
  ef1: i := 1;
  ef2: i := 2;
  ef3: i := 3;
  ef4: i := 4;
  else I := 0;
 end;
// Set Flags to use
 Flags := 0;
 if opShowDialogs then Flags := MAPI_LOGON_UI;
 if opUseSeparateSession then Flags := Flags + MAPI_NEW_SESSION;

 case MapiAddress(fMapiSession^,fDlgParent.Handle,@fLstCaption,I,@fToString,0,mrd2^,Flags,0,@t,mrd) of
  MAPI_E_FAILURE: Application.MessageBox(strERROR,'Error: MapiAddress',MB_OK+MB_ICONERROR);
  MAPI_E_INSUFFICIENT_MEMORY: Application.MessageBox(strMEMORYSHORT ,'Error: MapiAddress',MB_OK+MB_ICONERROR);
  MAPI_E_INVALID_EDITFIELDS: Application.MessageBox(strADDR_EDITFLDS ,'Error: MapiAddress',MB_OK+MB_ICONERROR);
  MAPI_E_INVALID_RECIPS: Application.MessageBox(strADDR_RECIP ,'Error: MapiAddress',MB_OK+MB_ICONERROR);
  MAPI_E_INVALID_SESSION: Application.MessageBox(strADDR_SESSION,'Error: MapiAddress',MB_OK+MB_ICONERROR);
  MAPI_E_LOGON_FAILURE: Application.MessageBox(strLOGIN_FAILED,'Error: MapiAddress',MB_OK+MB_ICONERROR);
  MAPI_E_NOT_SUPPORTED: Application.MessageBox(strNO_OP_SUPPORT,'Error: MapiAddress',MB_OK+MB_ICONERROR);
  SUCCESS_SUCCESS: Success := True;
  Else
   Application.MessageBox(strUNKNOWN_ERROR,'Error: MapiAddress',MB_OK+MB_ICONERROR);
 end;

 if success then Result := mrd^;

 MapiFreeBuffer(mrd);
 MapiFreeBuffer(mrd2);
end;

You cannot return the array of recipients. You have to process the array of recipients and then call MAPIFreBuffer. Eg:

var
  pNewRecipients : PMapiRecipDesc;

  MAPIAddress(fMapiSession^,fDlgParent.Handle,@fLstCaption,I,@fToString,0,mrd2^,Flags,0,@t,mrd); // your call
  pNewRecipients:= mrd;
  for n:= 1 to t do begin
    GetRecipentInfo(pNewRecipients^);
    Inc(pNewRecipients, 1);
  end;
  MAPIFreeBuffer(mrd);

The definition of GetRecipentInfo looks like this:
procedure GetRecipentInfo(mrd : TMapiRecipDesc);

Thats it. No more no less. Good luck!
