For whatever reason your SonicWall is responding to the Exchange Connectivity Request with it's own self-signed certificate (the one it generates when it first starts up - hence the IP address).

If that IP ( is the correct one to access your Exchange Server then you need to make sure that all HTTPS traffic on port 443 for that IP address is forwarded to your Exchange CAS.

try importing the certificate on the nokia phone using a cable or using OWA in the phone and try it

iphones are not much secure so they are ok when there is a certificate error but on the other hand nokia does not continue to proceed
