I cannot disable wireless calendar sync. I've tried doing it from the handheld's calendar options and the desktop manager, and after syncing a few times, wireless calendar sync is turned on again!

Any ideas how to permanently shut it off?

I have a 7250 and am using a BB Enterrprise server with MS Exchange.

You have 4.1 Desktop Manager. Put it on 4.0 sp1.

That's funny. There are quite a few of us who wish we had your problem. We can't get the wireless calendar to work properly with Exchange.
