Your error suggests you are NOT using SSL. Let me just go on record and say that anyone who does not use SSL for Exchange is just BEGGING to be pwned. With that said, go to
CA Cert and get a free server cert, or make your own with Win2k3. Then use the
Microsoft Disable Cert Checking program to turn off the certificate verification on the phone.
With Activesync you should always make sure that you can first sync when connected to a computer. If you can't, over the air will never work. So go back to that and eliminate the GPRS. Next, give us all of your settings for activesync. Tell us exactly what you are using (minus login and password info of course). If you don't feel comfortable advertising your FQDN of your Exchange server, PM it to me or something. But unless we can see your settings, not much we can do to help.
FWIW, the error you gave is not
on this site which seems to be the authority on ActiveSync.
Thanks for the tip on SSL, I wasn't using it before because I always came through VPN before I got this phone. So I went to CA Cert, got a cert and installed it. Then I downlaoded and ran the disable cert check program. Next I reset the permissions on all of the virtual directories to their default settings, exactly the settings from this site:

I'm still getting the same HTTP_400 error. I get it both over the air and directly connected to ActiveSync on my PC. It works the first time both over the air and through a USB connection. It also works once when I change between connection methods, reset the phone, or restart Exchange and IIS on the server. It also works randomly through manual sync.
My ActiveSync settings on the phone are as follows:
User Name:
Just my username, no spaces, no / or , and no @. Just plain username.
Password:
My password.
Domain:
mydomain.com
Save password
Server Name:
mail.mydomain.com
Checked off This server uses an SSL connection.
Address device using:
SMTP Address
Service Provider Name
Cingular
Device Phone Number
xxxxxxxxxx
Text Message Address
xxxxxxxxxx@mobile.mycingular.com
I'll send you more specific info via a pm Slacker.
Thanks!
