  1. Hello Stefan,

    We have installed online server installed on Windows server 2012 R2. It has not been patched since July 2018. Now will I be able to install the latest version and Nov 2022 CU for Office Online Server in our Windows Server 2012 R2 itself ? I ask this because, the minimum requirements for installing this Nov 2022 CU is specified as Windows Server 2016 in Microsoft Download Center.


    1. Hi Lakshmi,
      I don’t have such an old OS available to test.
      My recommendation would be to evaluate this in a test environment before applying in production.


      1. Hi Stefan,

        Thank you for your quick reply. My Office Online Server Build version is also not the latest. May I know if the latest build version of Office Online Server can be installed on Windows Server 2012 R2 itself or does it also require Windows Server 2016 ? I am not able to find that information anywhere.


          1. Thank you so much

  2. Hi stefen, i’ve currently installed OOS version 16.0.8471.8525, while installing update (November 2022 CU) i’m getting error “The expected version of product was not found on the system”. is the upgrade path valid or we need to install some intermediate version before installing Nov 2022 CU?

    Thanks in advance 🙂
