Files generated from Microsoft Office 2007 applications are not supported and therefore are not available for viewing on BlackBerry devices. 

Filenames from Office 2007 include extensions which are based on the Open XML format (.docx, .xlsx, .pptx).  These extensions are not currently recognized by the NotifyLink or DynoPlex applications.
