EWS Managed module broken with latest Exchange 2016 Cu9 RRS feed

  • Question

  • We have a managed EWS module that we develop and install.

    It supplements the information returned to Outlook from EWS when a free/busy request is made.

    It has worked from Exchange 2010 up until the latest Cu9 of Exchange 2016.

    The behavior has changed for context.Request.InputStream.

    Any interaction with it, even just context.Request.InputStream.length results in an empty request going into EWS. 

    The result is that even installing a version of our module that does nothing but peek at the length of the request breaks results in all free/busy requests showing no data for other exchange users.
