I would guess the problem is OWA being broken in its use of HTTP/1.1. In
particular the Expect: 100-continue feature to enable better persistent
connections. You can try toggling the ignore_expect_100 configuration
option (OFF is probably needed).

2.7 (and 3.1) only have partial support for that feature. With that
ignore directive to cause a quick reject or a client timeout to happen
(5 minutes a coincidence? ).
3.2 is needed to make chunking and continue work through Squid (avoiding
the timeouts).
  * in particular 3.2.0.8 is the most stable and production usable of
the 3.2 series.
