Activesync Contacts & calendar

[PPCFreak]

I must be having a brain dead moment but this is driving me nuts.

I want to pull the contacts and calendar items from my Exchange server (work) to my mobile.

BUT I do not want my contacts and calendar appointments from the mobile to be sync'd to my Exchange account.

Is this possible?

For the time being, I am cheating and doing a sync, then unchecking the items on the mobile.

EDIT: And yes, I have to do a Local backup of Contacts and Calendar so that when I uncheck them from Activesync I don't loose them ALL from the mobile device.
