Thanks for the reply Amos.

I could not start squid. From the messages file of Solaris, I saw the message:

I typed in the correct passphrase. The certificate was generated for Apache server with openssl. The self-signed cert was generated from openssl also.

Here is revised squid.conf. Thanks.

The basics of it are that Squid is what interacts with the client. So 
the public cert needs to be presented there on https_port.

What Exchange uses depends on what type of interactions happen there. 
It is probably safest to have self-signed certs with the self-signing CA 
trusted by Squid (on cache_peer) so it can verify Exchange, but this 
only works if the clients are not interacting directly to Exchange via 
other channels.

NP: Squid requires PEM format certificate files.

When you built squid you omitted --enable-ssl. Ensure you have openssl 
development library to build against and rebuild your squid. It should 
accept the SSL related config after that.
