I've got BES running on a SBS 2003 box, all works well.
I have one user who is on the office most of the time, so he'd like his tasks and calendar to synch to his phone, but not his email.
His phone is already set up through Enterprise Activation and it works fine, I just can't find the setting to disable email delivery to the device.
I've got Blackberry Manager 18.104.22.168 and know just the basics. I set it up, but I can't say I've done anything more than follow the BB instructions.
