Hmm i think you could go to the system pref, look for firewall, and add Word to the list that isn't allowed, i'm not sure if this will work. also, you could get little snitch and block it that way (although i have no idea how that works, i've just heard people talk about blocking ports with it?)
hope i shone some light on your situation, sorry if i didn't im only a noob afterall 🙁
