  1. Hi Stefan, is it normal that the fix for Office Online Server 2016 is the same as the one for 2019?

    1. There is only one Office Online Server which works with SP2016 and SP2019.

    1. Hi Aleks,

      yes but this fix was released on December 19th after the regular December CU which was released on December 11th.

      Cheers,

  2. Hi Stefan,

    Actually we have the SharePoint version 15.0.4927.1000 (last update June 2017) and we would like to install one of the latest security patchs.

    Can we install only the SharePoint security fixes released with December 2018 PU without install the CU for SharePoint 2013 ?

    If Yes, we need to launch the psconfig or only the security fixes and reboot the servers ?

    Thanks in advance.

    1. Hi Raphael,
      4927.1000 is May 2017 CU. That is an unsupported patch level. You have to install at least April 2018 CU to be supported.
      See here for details:
      https://blog.stefan-gossner.com/2017/12/13/updated-product-servicing-policy-for-sharepoint-2013/

      Aside of the supportability question, what you are trying to do does not make sense.
      SharePoint 2013 consists of more than 30 packages which are patched independently. In December 2018 we released only security patches for four of these components.
      You would miss out security fixes for all the other components released between May 2017 and December 2018.

      If you are not installing December CU you need to install the latest security fix for each of these 30+ components separately.
      This is a huge effort and a complicated process. For this reason we always recommend to install the Uber package of the relevant CU rather than individual Patches.
      See here for details:
      https://blog.stefan-gossner.com/2014/08/18/sharepoint-patching-demystified/

      Regarding PSConfig: you always have to run this after installing SharePoint fixes. Independent if these are full CUs or just security fixes.

      1. Hi Stefan,

        Thank you for your answer.

        I wasn’t aware of the end of support of May 2017 CU. Good point!

        I agree that it doesn’t make a sense to update only the 4 components. It’s effectively huge effort to upgrade separately the 30 components!

        In this case, maybe I should go on December 2018 CU to have consistent updates because from January to April 2019 CU, there is no Office web apps CU. The last one is on December 2018 CU. What do you advise ?

        Cheers,
        Raphaël

        1. We usually recommend to evaluate the latest CU rather than an older one. So you could install December CU for Office Web apps and April CU for SharePoint.

          1. Sounds great!

            So I will go for December CU for Office Web apps and April CU for SharePoint but may I need to deploy also the SharePoint security fixes for April 2019 or it’s included in the CU ?


          2. The April CU includes all security fixes released on the same or earlier dates.
