Exchange 2007 SSL/TLS requirements

I have a customer who is running SBS 2008 w/ Exchange 2007.  They are now required to pass PCI scans are are flagged due to the use of SSL 3.0 and TLS 1.0.  However, when I disable them using the MS KBs to make changes in the registry, activesync seems to stop working.

I am looking online for info about SSL/TLS requirements for Exchange 2007 but most of the hits reference either 2007/SSL 2.0  or SSL 3.0/Exchange 2010 or 2013.

Does anyone know if SSL 3.0 or TSL 1.0 are specifically required for Exchange 2007?

Thanks in advance

Found the answer finally.  In the below KB, MS says that out of the box exchange 2013 requires SL 3.0 and TLS 1.0 https://support.microsoft.com/en-us/kb/3045301

If Exchange 2013 has these requirements I expect that 2007 would be similar
