Not sure if this is problem with only the Lumia 925 or not, but it seems like the phone never stores the password and I have to re-enter it almost every time I tap the Exchange Tile, and the notifications on it are not updated most of the time, I'm curious to know if this is an issue with you guys as well? I'm not sure either if we are using Exchange 2010 or 2003 still my guess is 2010...
