EWS Response didnt contain valid XML. RRS feed

  • Question

  • Hi Folks,

    I have a routine that is using a call to FindFolders in order to locate get a list of the folders a mailbox has.  The call to FindFolders(WellKnownFolderName.MsgFolderRoot,...) is failing with an exception as follows:-

    "The response received from the service didn't contain valid XML"

    The inner exception contains the following:-

    "The expected XML node type was XmlDeclaration, but the actual node type is Element".

    My trace handler is logging the following response message:-

    "Server Error in /EWS application,  Configuration Error.    Could not load the file or assembly Microsoft.Exchange.Security, Version=14.0.0.0, ....."

    c:\Program files.....\EWS\Web.Config line 2393.

    Assembly load trace: Assembly manager loaded from c:\Windows\Microsoft.Net\Framework64\V2.0.50727\mscorwks.dll running under executable c:\windows\system32\inetsrv\w3wp.exe

    Running fuselogvw gives me the error GAC Lookup was unsuccessful.

    This routine was working but seems to have stopped for some reason, I have checked that the assembly is in the Exchange bin directory, the PublicKeyToken is correct (matches the web.config) - the version number is slightly different (14.0.3.123.3 - which I assume includes service packs).

    I have encountered this error testing against Exchange 2010 SP2 and Exchange 2010 SP3 and have used EWS 1.2 & 2.0.

    Does anyone have any ideas on the best way to go about resolving this issue?

    Regards

    Andy
