I purchased a GoDaddy Secure Certificate for my company back in February to install on our Exchagne 2003 SP2 server. I chose this certificate because i would not have to install a certificate on all the mobile devices that connect to Exchange. Recently, I purchased this same GoDaddy certifcate for another companies Small Business Server. There mobile devices are saying there is an issue with the servers security. Webmail works fine without any certificate warings, but any mobile (exchange activesync or OMA) is saying invalid certificate. Any ideas?
