Gibra, thanks by the information but for any reason I don't have the MAPI installed in my computer (windows 7 starter SP1).

But before I try to install MAPI I discovered that in Windows 2008 R2 server doesn't exist the file CDOSYS.DLL.

And I found this HotFix information from microsoft support: http://support.microsoft.com/kb/982720/en

I hope this solves my problem.

Thanks for help!
