ExRCA OOF connectivity tests failed


  • OOF failing in Outlook 2007 and greater.  ExRCA giving "ExRCA wasn't able to retrieve and confirm user availability.  There was an invalid XML response. If the Client Access server is running Windows 2008, try installing KB951847."

    Hotfix from installed on CAS and server rebooted.

    All other ExRCA tests passing.  All Outlook AutoDiscover tests passing.

    I'd really appreciate any advice and/or suggestions on this one!!

  • Can you see if in add\remove programs if you have .netframework 3.5 with SP1? Since the hotfix applies to both .netframework 2.0 and 3.5sp1 it woud've installed if you have either or. If you don't have 3.5 with SP1, download the SP1.

  • Awesome James.

    I updated all three versions with the downloads from that KB article, and everything sprung into life.

    My ExRCA tests are 100% successful, and I can see the OOF dialogue now in Outlook.

    Your help is greatly appreciated!  Many thanks for sparing the time.
