I have an SBS2008 server, I was receiving emails on my iPhone 3G with no problems, it was syncing with my exchange mailbox fine. It has now stopped working.
I ran the exchange connectivity test and receive the following results:
ExRCA is testing Exchange ActiveSync.
The Exchange ActiveSync test failed.
Attempting to resolve the host name mail.companyname.co.uk in DNS.
Host successfully resolved
Testing TCP Port 443 on host mail.companyname.co.uk to ensure it is listening and open.
The port was opened successfully.
ExRCA is testing the SSL certificate to make sure it's valid.
The SSL certificate failed one or more certificate validation checks.
The certificate name is being validated.
Certificate name validation failed.
Tell me more about this issue and how to resolve it
