Bare in mind, MS Word is a product intended for use in writting for "business" nd not necessarily the next great American novel. Active voice is currently encouraged in the Corporate world because it quickly identifies responsibility, causality, and makes it easier to take action compared to the fuzzyness of the passive voice. On the other hand, passive voice is just the thing you need in the Corporate world to avoid blame, fingerpointing, and regressive office politics - so there's a fine line to draw there as to when to use it.

Personally the MS Grammer Checker's ability to pick out Passive Voice sentences is a pet peeve of mind, especially when it results in my boss requesting things be rewritten (something must be wrong if there's a green underline). Usually though, the problem is rectified by using his name as the subject in disputted the sentence.
