Thanks for the reply, Zip, I heard the same thing from RIM (glad they are on the same page!
They said there is no way, via IT Policy, to encrypt existing files on a media card. He did say that users could move the files off the card and then back onto the card and they would then be encrypted. Yea, right, that'll happen right after I win the lottery.
The security guy isn't very excited about this, but is going let me invoke the encryption vs. disabling the card, pending further research - like how many of our users are already using cards.
My next step is to see if there is a way that I can find out how many users have media cards. Anyone know of a way to check this from the BES???
