After updating Exchange 2013, the EWS connection might not work in contentACCESS

PROBLEM:
After updating Exchange 2013 to CU15 (maybe older CU as well), the EWS connection might not work in contentACCESS.

SOLUTION:
After updating the Exchange Server, please test again the EWS connection on each Email archive. If you receive the error: (413) Request Entity Too Large, then it is necessary to update the EWS configuration on each CAS server:

  1. Back up file
    C:Program FilesMicrosoftExchange ServerV15FrontEndHttpProxyewsweb.config
  2. Replace the "uploadReadAheadSize" 0 value with 1048576 (bytes)
    serverRuntime uploadReadAheadSize=”1048576″
