Can windows 8 release preview 64 bit manage exchange tab in ADUC? I'm trying to enable exchange tab in ADUC but still no hope. I'm trying method that user for win7 64 bit but nothing happen. Step that trying 1. install ESMVISTA.msi /qb 2. try launch dsa.msc /32 got error An attempt was made to reference a token that does not exist. But in windows 8 32 bit, it work well and show exchange tab by normal install.
