What we have is an SBS 2011 SP1 and exchange 2010 SP3. (Also i'm testing this all on a test server right now)
We are trying to be compliant with PCI and using a scan from trustwave to determine if we are. So i found this nifty tool from https://www.nartac.com/Products/IISCrypto/
called IISCrypto40 which basically does all the disabling and registry changes that need by selecting what i want. So i click PCI and it left a box checked fro TLS 1.0. So I uncheck the box for TLS 1.0 and basically exchange stops and I knew this before i clicked it that remote desktop stopped working as well. Well RDP is not a big deal i have other tools i can use to remotely log onto the server.
So back to the main problem PCI compliance and disabling TLS 1.0 to become compliant seems to break exchange (Well at least OWA and remote connections from my smart phones so IIS problem). What do I need to do in order to use TLS 1.1 or TLS 1.2 for OWA and remote connections to work?
