Ok trying to get my pre to sync up with my exchange server. It's really weird it will work when i am on the local wireless. but as soon as i shut it off to use it it won't sync. I have tried ever combination of addresses. My friends got connected to it no problem with their BB's. Any suggestions? I have it set up for HTTPS have the certs on the phone and everything. I am getting restless on what to do. I can access via webmail and everything. Someone please help,

Ty in advance
