I was having the exact same problem as above.  The only way to resolve it was to reinstall the CAS, which was a pain, but it is working perfectly now.

You can also remove the directory:

C:\WINDOWS\Microsoft.NET\Framework64\v2.0.50727\Temporary ASP.NET Files\microsoft-server-activesync

You must stop the application pool before. That solved the problem for me.
