The general approach is to look at the original mail containing the
documents in a text editor (or Gmail's "Show Original") and search for
the Content-Type headers.  They'll look something like this:

Content-Type: application/vnd.openxmlformats-officedocument.wordprocessingml.document; name="some junk from the boss"

Most likely that's the one you want most.  Add

application/vnd.openxmlformats-officedocument.wordprocessingml.document

to Pass Mime Types and you'll probably get most of them.  However, not
all mail programs conform to the registered types.  There may be
others you want to catch, but you'll have to investigate them
yourself I suspect.
