This has probably been addressed, but I didn't see anything in the search... Are others having problems getting exchange accounts working or am I late to the party on something? Anyway, I just changed roms on two devices. Exchange works fine on the phone, but not with this rom.
Edit: Problem solved and unrelated to the rom.
The server has a 10 mobile device policy limit that was exceeded. Old and unused devices/roms had to be manually deleted from the device list and the problem was solved.
