I'm trying to put music on my Storm, but I'm setting a Mass Storage Mode is turned off. How do I turn it on? My storm is connected to a BES server at work - could this be preventing me from putting music on my Storm?

It is possible. Also, do you have a microSD memory card inserted?

Options/Memory/Auto Enable Mass Storage Mode When Connected:
Select either On or Prompt. Prompt will prompt you to turn it on or off every time you connect it to your computer.

Your BES admin may have set a policy not allowing mass storage on their sever in which case you will be out of luck using this feature unless you convince them to change the policy.

Yeah our BES policy at work is like a catholic mother.
I took my phone off the BES.
