Naive children, open sesame will not open any of these doors. And as Phoebe James, Apollo Adara-Stark, and Curtis Fuller would soon find out, Alohamora will not do you any good either.

It is not until the loud Bombarda is cast by the flying first year (Atlas Flamsteed) that one of the side-doors flies open, a large hole where the doorknob used to be. Go on, venture inside. It looks like this used to be a large storage closet in a previous life. Much like the office itself, there isn't much inside, but you will find lots and lots of empty, wooden crates.
