I'm working to get our Exchange servers in compliance with PCI. I have tried a manual disable of SSL 3 on our CAS\HUB servers as well as Crypto40.
Whenever I disable SSL3 on the servers, clients can no longer access OWA or see free/busy when scheduling. There may be other functions not working, but this was enough, so i restored SSL3 for now.
What am i missing? IS there a server or client side setting I need to tweak to allow the disabling of SSL in favor of TLS?
As a note, I have disabled SSL 1, 2 and 3 on my workstation as well.
Any suggestions would be greatly appreciated.
