Exchange 2013 - looking for guidance with owa issues

Hi Marco, Exchange 2013 CAS are stateless. That means that no persistence, aka session affinity, is required: http://technet.microsoft.com/en-us/library/dd298114(v=exchg.150).aspx

The only situation that may require persistence is the case of Office 365 migration using the MRS Proxy.

Is the connection to the CAS getting past the SSL handshake? Does your FastL4 configuration break if you disable persistence there?

thanks
