One of my coworkers in the IT department renewed the certificate on the exchange server 2003. After renew, all iphones in the company can't retrieve their emails.

I used the test tool: https://www.testexchangeconnectivity.com/#&&v5i2iAnCJChhVE6++cacUpPTGrs5QPa+X0lS0igiutd8hfjFgzVDW6gQkz4iH8UhMNDxtD1X8K0srNbEhGksHzsAF8D9MV7nVZV6yZr7qXqhLo1ahzMd3POcVezdXMdm3r2qmHe4cTMNXE7YRJ1PqrcFSbmthIXRNJe1ZYu0Zh50lKtrqiZ45MJT6Q1BwnWquNo6zQ==

and the result shows:
"Testing the SSL certificate to make sure it's valid.
       The SSL certificate failed one or more certificate validation checks."

I attached the print screen for this error. Also, i did a port test on http://www.yougetsignal.com/tools/open-ports/, the result says the port "Port 443 is closed on XXX.XX.242.131."

this is the report from the testexchangeconnectivity.com. I checked another article on EE, it's this one: https://www.experts-exchange.com/Software/Server_Software/Email_Servers/Exchange/A_1798-Exchange-2003-Activesync-Connection-Problems-FAQ.html.


Dear experts here, could you please help me with this. I know it's new year eve and most of you maybe stay at home enjoying time with your families. But I really don't want to my coworkers isolated with company email.

thank you.
