Thanks for the reply Amos. I could not start squid. From the messages file of Solaris, I saw the message: May 9 11:04:20 socksnj squid: [ID 567784 local4.alert] Exiting due to repeated, frequent failures May 9 11:15:48 socksnj squid: [ID 702911 user.alert] Failed to acquire SSL private key '/opt/squid-3.1.19/etc/webmail_test.key': error:0906406D:PEM routines:PEM_def_callback:problems getting password May 9 11:15:51 socksnj squid: [ID 702911 user.alert] Failed to acquire SSL private key '/opt/squid-3.1.19/etc/webmail_test.key': error:0906406D:PEM routines:PEM_def_callback:problems getting password May 9 11:15:54 socksnj squid: [ID 702911 user.alert] Failed to acquire SSL private key '/opt/squid-3.1.19/etc/webmail_test.key': error:0906406D:PEM routines:PEM_def_callback:problems getting password May 9 11:15:57 socksnj squid: [ID 702911 user.alert] Failed to acquire SSL private key '/opt/squid-3.1.19/etc/webmail_test.key': error:0906406D:PEM routines:PEM_def_callback:problems getting password May 9 11:16:00 socksnj squid: [ID 702911 user.alert] Failed to acquire SSL private key '/opt/squid-3.1.19/etc/webmail_test.key': error:0906406D:PEM routines:PEM_def_callback:problems getting password May 9 11:16:00 socksnj squid: [ID 567784 local4.alert] Exiting due to repeated, frequent failures 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.

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 I ran 'squid -X', I got the > below message stating 1. unrecognized: 'https_port', 2.

Ensure you have openssl development library to build against and rebuild your squid.
