Microsoft campuses were always impossible to navigate. The buildings are numbered in the Japanese style, i.e. chronologically.
Why not number buildings on a battleship grid? Building B6 must be adjacent to A6 and B7, as opposed to building 40 being adjacent to 27. Why not prefix the office numbers of an X-wing building with cardinal directions? If you see office N202, and you need office W107, head to the core, down the stairs, and one hallway to the left.
Not to mention that some people always used the golf course code names for clusters of buildings, too... which were never "official" so there wasn't even any signage or anything to refer to for those. I remember being pointed to a pile of "stuff new people ought to know but HR won't tell you" on some random share in NTDEV when I started and it had a map with those marked on it.
The main Redmond campus was shared with other tech companies originally.
Microsoft grew outwards from the original 4, then 6, buildings. I guess they didn't think it'd be worthwhile to rename the buildings once they expanded beyond 4 or 6.
