What are the features of successful user for Microsoft office programs?

I am not really sure what exactly you mean but I guess you are asking what skills a user of MS Office will obtain?

MS Office Applications are not that hard. The most important applications that everyone must be aware of, at least in my humble opinion area: Word, Excel, Outlook and Power Point. These are the basic applications/programs. Most if not all companies will ask for MS Office Experience and it is needed in the market, everyday.
