I doubt the same certificate used on the https_port will work as both server and client certificate. Perhapse that is why the verification has to be fully disabled. > acl exch_domain dstdomain office.abc.com > acl exch_path urlpath_regex -i /exch(ange|web) > acl exch_path urlpath_regex -i /public > acl exch_path urlpath_regex -i /owa > acl exch_path urlpath_regex -i /ecp > acl exch_path urlpath_regex -i /microsoft-server-activesync > acl exch_path urlpath_regex -i /rpc > acl exch_path urlpath_regex -i /rpcwithcert > acl exch_path urlpath_regex -i /exadmin > acl exch_path urlpath_regex -i /ews > acl exch_path urlpath_regex -i /oab > acl exch_path urlpath_regex -i /autodiscover > cache_peer_access exchangeServer allow exch_domain exch_path > cache_peer_access webServer deny exch_domain exch_path > never_direct allow exch_domain exch_path > cache_mem 32 MB > maximum_object_size_in_memory 128 KB > access_log stdio:/var/log/squid/office-access.log squid > cache_log /var/log/squid/office-cache.log > cache_store_log stdio:/var/log/squid/office-cache_store.log > pid_filename /var/run/squid-office.pid > visible_hostname office.abc.com > deny_info TCP_RESET all > http_access allow all > miss_access allow all > icp_port 0 > snmp_port 0 > > > > cache.log > Jan 01 10:33:35 1970/12/10 16:15:42 kid1| Process ID 5631 > Jan 01 10:33:35 1970/12/10 16:15:42 kid1| Process Roles: worker > Jan 01 10:33:35 1970/12/10 16:15:42 kid1| With 1024 file descriptors available > Jan 01 10:33:35 1970/12/10 16:15:42 kid1| Initializing IP Cache... > Jan 01 10:33:35 1970/12/10 16:15:42 kid1| DNS Socket created at 0.0.0.0, FD 6 > Jan 01 10:33:35 1970/12/10 16:15:42 kid1| Adding domain > yieldbroker.com from /etc/resolv.conf > Jan 01 10:33:35 1970/12/10 16:15:42 kid1| Adding nameserver > 10.32.20.100 from /etc/resolv.conf > Jan 01 10:33:35 1970/12/10 16:15:42 kid1| Adding nameserver > 10.32.20.102 from /etc/resolv.conf > Jan 01 10:33:35 1970/12/10 16:15:42 kid1| Logfile: opening log > stdio:/var/log/squid/office-access.log > Jan 01 10:33:35 1970/12/10 16:15:42 kid1| Local cache digest enabled; > rebuild/rewrite every 3600/3600 sec > Jan 01 10:33:35 1970/12/10 16:15:42 kid1| Logfile: opening log > stdio:/var/log/squid/office-cache_store.log > Jan 01 10:33:35 1970/12/10 16:15:42 kid1| Swap maxSize 0 + 32768 KB, > estimated 2520 objects > Jan 01 10:33:35 1970/12/10 16:15:42 kid1| Target number of buckets: 126 > Jan 01 10:33:35 1970/12/10 16:15:42 kid1| Using 8192 Store buckets > Jan 01 10:33:35 1970/12/10 16:15:42 kid1| Max Mem size: 32768 KB > Jan 01 10:33:35 1970/12/10 16:15:42 kid1| Max Swap size: 0 KB > Jan 01 10:33:35 1970/12/10 16:15:42 kid1| Using Least Load store dir selection > Jan 01 10:33:35 1970/12/10 16:15:42 kid1| Current Directory is /etc/squid > Jan 01 10:33:35 1970/12/10 16:15:42 kid1| Finished loading MIME types and icons. > Jan 01 10:33:35 1970/12/10 16:15:42 kid1| HTCP Disabled. > Jan 01 10:33:35 1970/12/10 16:15:42 kid1| Configuring Parent 127.0.0.1/443/0 > Jan 01 10:33:35 1970/12/10 16:15:42 kid1| Configuring Parent 10.32.69.11/443/0 > Jan 01 10:33:35 1970/12/10 16:15:42 kid1| Squid plugin modules loaded: 0 > Jan 01 10:33:35 1970/12/10 16:15:42 kid1| Adaptation support is off. > Jan 01 10:33:35 1970/12/10 16:15:42 kid1| Accepting reverse-proxy > HTTPS Socket connections at local=202.74.32.15:443 remote=[::] FD 11 > flags=9 > Jan 01 10:33:35 1970/12/10 16:15:43 kid1| storeLateRelease: released 0 objects > > > cache log > Dec 10 16:16:23 2015.225 RELEASE -1 FFFFFFFF > BE6736C8CD1A74A54575AF9880395D04 ?

I am a little suspicious about the particular methods that are failing for you are non-HTTP methods. Are you able to try running the latest Squid with a patch?
