Lets see if I can explain this one.
Here are the basics first.
I have a Thawte cert installed on my Exchange 2K3 SP2 Enterprise server and
my ISA server.
WHen i connect either through USB or WiFi in my office all of our WM5 device
work fine. but as soon as I try to connect through GPRS/CDMA or external WiFi
I get the 85010004 error stating the user account doesn't have permissions. I
am thinking the failure resides in how I have ISA setup.

On ISA I have an HTTPS listener passing info the exchange server.

any help would be great.
