ie11 against exchange 2010 [petrosyan mode on]

[swdukk]

сначала столкнулся сам. теперь читаю кавайную заметку:
http://connect.microsoft.com/IE/feedback/details/792398/exchange-2010-owa-will-only-run-light-mode-in-ie11

приведу всего две цитаты которые заставлять меня плакать:
1. This is an Exchange 2010 issue, not an IE11 issue. Exchange 2010 reads the User Agent String instead of using feature detection (going against the IE development team's recommendations).

2. Posted by Microsoft on 08.07.2013 at 11:11                                       
We are currently unable to reproduce this issue as described.
Best regards,
The Internet Explorer Team

as Not Reproducible

Update: впрочем connect.microsoft.com и сам не работает в IE11 (кнопка i can reproduce too). Бугага
