SSL Certificate problems on Windows Mobile 5...
Posted on 2006-05-18
I continue to get a not trusted certificate error on a Cingular 8125 - Windows Mobile 5 device when accessing OMA as well as an error when synching through Micrsoft ActiveSync. I have number of Treo 650s and Samsung PCH-i600s which work just fine through ActiveSync with SSL enabled.
The SSL certificate on the Exchange server was issued by InstantSSL/Comodo Group. I have the root and intermediate certificates properly installed on the server (as evidenced by the other devices working). I have installed three root certificates from the InstantSSL website on the Cingular 8125 using instructions from this site. The 8125 works fine with SSL disabled. Also, the certificate error gives green checks to date and server name, only "not chosen to trust" error.
I am completely at a loss here. Any help would be appreciated.
