We have an issue with our TMG array where one of the servers doesn't display outlook.com/hotmail/other microsoft bits and bobs correctly. For example, I log into my hotmail, and I get a page that looks like this

Clik here to view.
however the same page accessed through the second server in the array displays fine. The arrays (obviously) share the same config and both are Up-to-Date and synced.
Things we've tried so far....
Each proxy has an individual NAT to an external IP address - we've changed these and swapped them over, but the errors always happen via PROXY1 - so it wouldn't appear to be any IP blocking on MS part
It does appear to work the first time you login, but after that, you get the incorrectly drawn page
If you change the URL from dub110 to dub109/dub122 then it appears to redirect ok to dub110 and display correctly. Subsequent refreshes give you the junk page.
Other MS 'live' sites do seem to have wierd issues through PROXY1 - for example the picture is missing off the login.live.com page via PROXY1
So, given that both TMG servers in the array are sharing the same config, what can be happening? No Dashboard alerts, no AD issues, all connection verifiers show ok etc etc.....
Thanks in advance
