ActiveSync with SSL

By Rvickers78 ·
This past weekend I enabeled SSL on my Exchange 2003 server running on Server 2003. Now every time one of my users with the Smartphone connects they get the message Synchronization failed. The Security certificated on the server in invalid. contact your system administrator to install a valid certificate on the server and try again. Error Code INTERNET_45.

Does this have something to do with my using my own certificate that I made on the server? Any help would be greatly appreciated.

INTERNET_45
INTERNET_45 (ERROR_INTERNET_INVALID_CA): Synchronization failed. The security certificate on the server is invalid. Contact your system administrator or ISP to install a valid certificate on the server and try again.
Explanation: The synchronization client tried to validate the certificates, but it detected that a certificate that is not valid is installed.

User Action: Install a valid certificate on the server, and then try to synchronize again.

By default, the following root certificates are installed on Pocket PC 2002 devices.
Verisign Class 1 Public Primary CA
Verisign Class 2 Public Primary CA
Verisign Class 3 Public Primary CA
Verisign Class 3 Public Primary CA (202
GTE Cybertrust ROOT
GTE Cybertrust Solutions ROOT
Thawte Server CA
Thawte Premium Server CA
Entrust.net Secure Server
Entrust.net CA (2048 bit)

If you are using a certificate that is not trusted, you can turn off certificate validation on the device by using a .cab file that is provided in the Support\Tools\Disable SSL folder on the Microsoft Mobile Information CD. Copy the AS_Cert_OFF.cab file to your device, and then run the program on your device.


You would need to trust the CA of your certificate on the server.
