It has been going on recently since early August and continues throughout today.
Microsoft has had issues with cloaking their bots in the past and fixed them. Is it possible they are breaking into bad habits once again?

Currently, straight out of my logs...
188.8.131.52 - - [05/Aug/2010:15:45:09 -0700] "GET /dir/filename.html HTTP/1.1" 403 1468 "-" "-"
No UA, no robots.txt, no REF, no nothing. Not once. Not twice. Not even three times. Try eleven.
After about a month, one member said:
I cannot believe the lack of response to this thread.
Microsoft bot IP is compromised and being used by non-bot UAs, possibly even has been hacked, and NO response. Amazing.
So how about it Microsoft? What is the answer?
