invalid certification error when syncing to Exchange 2007

I kept getting an error that the certificate on the server was invalid, and I
was told that I had to switch my data plan to the "enterprise" plan.. which I
did.. still does the same thing. However, if I plug my phone in at my office
(PC connected to the corporate network) via USB, my exchange account starts
working even after I unplug it. But if I reboot my phone (ATT Tilt WM6.1) or
stop the ActiveSync process and restart it.. it goes back to the
certification error.. do I need to request a certificate from my Exchange
administrator or something?..

Can you access OWA or OMA from the Internet using SSL? Is it code
0x80072F0D. Or this link may help.

Hi,
Check the certficate on the desktop and see if it is a public or private
cert. This is done ine IE and look at the properties of the page and then
select the certitifcate.

If it is a public cert, you may need to install the root cert from the CA.
If it is a private cert, you can export the cert on your PC in IE and then
import it into your device.
