I am using Word 2003. I am working in a file that is not originally mine. I
need to accept all changes made, but in the Reviewing tool bar, accept
change, reject change, and accept all changes is grayed out. I also tried to
right click on each addition and deletion, and accept and reject change is
grayed out there too. I just want to accept all changes made; I do not need
to review them. How can I do this?

Thanks!
