Exchange 2010 Activesync not working

I just migrated from Exchange 2003 to Exchange 2010 yesterday. Everything is working except for Activesync.  Any help would be appreciated.
I went to testexchangeconnectivity.com to test it and here are my results:

ExRCA is testing Exchange ActiveSync.

The Exchange ActiveSync test failed.

Test Steps

Attempting to resolve the host name mail.mydomain.com in DNS.


The host name resolved successfully.

Additional Details


Testing TCP port 443 on host mail.gsp-kc.org to ensure it's listening and open.


The port was opened successfully.

Testing the SSL certificate to make sure it's valid.

The SSL certificate failed one or more certificate validation checks.

Test Steps

ExRCA is attempting to obtain the SSL certificate from remote server mail.gsp-kc.org on port 443.

ExRCA successfully obtained the remote SSL certificate.

Additional Details

Validating the certificate name.


The certificate name was validated successfully.


Additional Details

Validating certificate trust for Windows Mobile devices.

Certificate trust validation failed.

Test Steps


ExRCA is attempting to build certificate chains for certificate CN=MyDoman.local, OU=IT, O=GSP, L=Kansas City, S=Missouri, C=US.

A certificate chain couldn't be constructed for the certificate.

Additional Details

The certificate chain couldn't be built. You may be missing required intermediate certificates.

It says that the certificate is not from a trusted source.
Get a third party certificate., or if you have it in 2003 move it to 2010..

None of the above seemed to help. If it helps, when attempting to configure active sync on the client phone the following errror is encountered when use ssl is selected:
unable to open connection to server due to security error
If I uncheck this, I get the following error:
Username or password is incorrect
(Authentication failed)

Check whether inheritance is disabled on the problem users:

1. Open Active Directory Users and Computers.

2. On the menu at the top of the console, click View > Advanced Features.

3. Locate and right-click the mailbox account in the console, and then click Properties.

4. Click the Security tab.

5. Click Advanced.

6. Make sure that the check box for "Include inheritable permissions from this object's parent" is selected.

Yep.. Already checked that. And this is occuring for all users.
lucid8Commented:
1. Do you mean that the  "Include inheritable permissions from this object's parent" is selected for all users?

2. Have you obtained and installed the appropriate 3rd party SSL certificates

3. Have you attempted to login via a device?  I see you used testexchangeconnectivity.com  which is great but not always 100% accurate, i.e. testexchangeconnectivity.com  fails on my site but my Activesync users can get in just fine.

4. If yes on the devices, which type and how are you entering the login criteria, i.e. FQDN or ??
JpiggeesrAuthor Commented:
1. Yes,
2 Actually, I used a privately signed certificate,
3. Basic driod and Iphones
4. login criteria is "\username", PSWD, mail.mydomain.com

Other than the AutodiscoveryHTTP redirect virtual directory, everything else seems to be covered.
