I just want to start off saying I've done an exhaustive search of this issue on the internet, Microsoft KB and this site as well. I have a Cingular 8125 upgraded to the newest firmware. I have an Exchange 2003 server that is also an internal CA and I have self issued certificate for my FQDN for SSL. When I browse to the OWA website I get the SSL certificate screen telling me it's an untrusted authority and when I click yes it goes through. When I browse to the OMA page a desktop machine I get the SSL certificate screen and when I click yes I just get a white screen, no errors nor a logon screen. On the 8125 the SSL screen never comes up. When configuring Activesync I get the error 0x80072F0D. I've copied the root certificate over and when you double click it says "Cannot access certificate". I have tried using AddRootCert.exe and it says "Error 0 Opening File" when I try to choose the cert. I've tried using SmartPhoneAddCert.exe and put the cert in a Storage folder like described by MS but it errors with "Unable to locate any certificate files". I finally exported my certficate to a .pfx file and used p12import to import the files. After this I don't get the SSL certificate window for OWA but still nothing on OMA or Activesync. I really need to get Activesync working with this self issues certificate. Thanks in advance.
