Hello Friends,

ActiveSync, which works internally, but not externally.

We are using exchange 2010 SP2 and Exchange Certificate is our internal root CA.

When I have test the Activesync using https://www.testexchangeconnectivity.com , getting error: " 

Testing the SSL certificate to make sure it's valid.
The SSL certificate failed one or more certificate validation checks.
Validating certificate trust for Windows Mobile devices.
Certificate trust validation failed.
Test Steps
ExRCA is attempting to build certificate chains for certificate CN=mob.domain.com.
A certificate chain couldn't be constructed for the certificate."

Please advice me to resolve/ work activesync from externally aswell.
 






Additional Details

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