0x80072F0D in Mobile Active Sync Device

We have an Exchange 2003 SP2 Front end server that has been running OWA over SSL with no problems. I am now trying to Mobile Access to work with my Cingular 8125. When trying to sync the error is "The security certificate on the server is invalid...." Error code 0x80072F0D.

1. I can successfully hit https://myserver.com/oma and login and view the directory.
2. The certificate is a new valid cert from Comodo.
3. The cert is issued to the proper public domain name.

I followed the MS instructions http://www.microsoft.com/technet/itsolutions/mobile/deploy/msfpdepguide.mspx to setup for Mobile use.

Help!
Thanks

If you hit OMA with Pocket IE on the device, do you get a security warning?
I don't believe that Comodo certificates are trusted natively by the Windows Mobile device, which would explain the security warning.

You are correct, if I hit https://myserver.com/oma with IE I do get a security warning that "The cert was issued by a company you have not chosen to trust." Comodo uses GTE Cyber Trust as the Root cert, which is preinstalled on Mobile 5.0. Not sure what to do from here, but I am contacting Comodo support to get their take on it.

Are they using a chained certificate?
You have to make sure that it is the correct root certificate. Most of the certificate suppliers have a long list of them.

Geotrust (for example) have loads of them: http://www.geotrust.com/resources/root_certificates/index.asp
But only one is in the Windows Mobile device.

I think you are correct as Comodo is not on this list: https://partner.microsoft.com/global/partner/40027352

I tried installing a root cert according to http://support.microsoft.com/kb/915840/en-us but with no luck. When I use the spaddcert.exe it cannot find the cert I have copied into the "Storage" folder. Microsoft says contact the OEM of the device. Cingular's KB has very little info and says to contact Microsoft! This is starting to be highly annoying!
