   Hi Stefan,

   I’ve noticed this is the latest update for Office Online. Has the release schedule changed?

   Also, I noticed on the KB5002470 link it says DO_NOT_USE_Office Online Server underneath the page header. Is there anything to be concerned about here?

   Kind Regards,

   Chris

      Hi Christopher,
      the DO_NOT_USE_… part is just a taxonomy hint. You can ignore that.
      Office Online Server updates are mostly released when security fixes are made available. The last such update was in September – thats why there was no fix in the latest months.
      Cheers,
      Stefan

   Is there a webpage that lists all the CU and download links for Office Online Server. I am hoping I could go to such a page and download manually what I want.
   MS lists all the SharePoint versions and their monthly patches. Does such a thing exist for OOS?

   Thanks for doing this and your efforts.

   Richard

   Hello!
   I am not seeing recent Office Online Server updates since September 2023. However, I noticed that Office Online Server seems to be combined with the SharePoint CU on the catalog download site. I do not have the OOS and SharePoint installed on the same server, should I? I have OOS on its own server.

      Hi John,
      SharePoint and Office Online Server need to be on different machines.
      Cheers,

         Hi Stefan!
         Thank you for your quick response! Much appreciated!
         I do have them on separate machines, but my original question remains. Are there new updates for OOS out there? I used to see them about monthly in your emails. I have not seen one for a few months. They are now showing up on the same update on the Microsoft catalog site.
         Can you clarify why they show up on the same update? Here is my search results page.

            Hi John,
            the latest fix was released in September 2023.

   Hi Stefan,
   That is perfect! Thank you so much! Sorry for the confusion on my part, security is so important now I wanted to make sure I was not missing some change I did not know about.

   Best regards,
   John
