I have a Moto Q that I recently upgraded to the latest AKU2 firmware release
from Motorola. Since upgrading I have been unable to connect and synch to my
exchange server. Everything worked great until I upgraded. Now I get an
error message (SC 85030028), which says "Cannot obtain a valid certificate."

Our exchange server is using a Go Daddy/Starfield certificate which is one
of the supported root certificates on the Q. It is installed as a root cert
on the Q. I have tried installing the intermediate certificate as well, but
so far no joy. Is there something in AKU2 that has changed the way WM5
authenticates with exchange activesync and is the Valicert cert no longer
supported despite saying so to the contrary on the MSDN site?

Thanks,
Jonathan
