Yes I believe LucasCruikshankLover is correct.It is the final farewell season of the show. You should write to each cast member separately using their fan mail addresses

I could be wrong, but I think they've finished shooting the series. It seems far enough into the last season that shooting would be over. I've seen previews for upcoming movies with some of the actors from the office, so I think they're done shooting. I definitely could be wrong; I haven't seen any stories on them wrapping filming, but I don't know. That's what I think at least.

I was wondering if anyone has the set of the office address.
Thanks
