When I'm trying to sync with WM2003 or WM5 I'm always getting an Error like "INTERNET_45" respectively "0x80072F0D" (Invalid certificatae).
However I have been follwing the procedure described in kerio manual. I'm able to download the certificate and I am also able to install them. After that they are listed as root certificates.
Also if I'm visiting the website with Pocket Internet Explorer on mobile device I have to confirm all the time to accept the certificate.
The certificates have been ordered by europeanssl dot eu.
I have some suggestions for you,
Export certificate form KMS. default this will be ".CRT" format. rename this to ".CER" format.Copy this file by any means to your mobile device, and click on, this will install the certificate to your device. NOW SYNC Will work.
if you use Secure Connection for Active SYNC, this is mandatory. or you can still use unsecured.Secured uses 443, and unsecured uses 80, so open both the ports in the firewall.
with best regards,
