PCI Compliance, Disable TLS 1.0 on Exchange 2013 brakes OWA


I'm trying to pass PCI compliance and one of the requirements is to Disable TLS 1.0 on Exchange server.
My version of Exchange is 15.0 (Build 1076.9) and I have successfully disable SSL 3 and 2 but when I disable TLS 1.0  exchange stops working. I have seen some posts that Microsoft has advised against disabling TLS 1.0 but this is necessary for the PCI compliance. Anyone knows about any workarounds or solutions to get the PCI compliance passed.

Thanks ,

Make sure the update that supports TLS 1.2 for Exchange server 2013 has been installed.

Yes I have CU8 installed that allowed me to disable SSL 2 and 3 even after update when I disable TLS1.0 OWA stops working.

it looks like CU8 will not allow you to disable TLS1.0 without affecting exchange functionality but with SSL 2 and 3 disabled and TLS 1.0 enabled I can pass PCI compliance scan. I have Just used IIS Crypto by nartac software and selected PCI button rather then manually make changes. Run the PCI compliance scan and it worked.
