I'm sorry for thread - the problem was in horde/config/mime_drivers.php: $mime_drivers_map['horde']['registered'] = array( 'php', 'tgz', 'vcard', 'msword' ); I just added 'msword' and it solved the problem. It was commented by default. Thank you Jan. Regards, Roman -- "Jer ono sve sto znas o meni to je samo stara prica - ja sam jedan od mladica koje vidjas svaki dan" - Arsen Dedic
