September 2023 CU for SharePoint Server Subscription Edition is available for download

The product group released the September 2023 Cumulative Update for SharePoint Server Subscription Edition.

Monthly SharePoint Server Subscription edition updates are released as a single unified “uber” package containing both the language independent and language dependent fixes. Language independent and language dependent fixes will no longer be released separately. This is similar to the full server packages released for SharePoint 2013.

The KB article for September 2023 CU will be available at the following location in a couple of hours:

  • KB 5002474 – September 2023 Update for SharePoint Server Subscription Edition
    This is also a security update!

The download for September 2023 CU is available through the following link:

It is irrelevant which language you pick on the drop down in download center. It will always download the same package.

After installing the fix you need to run the SharePoint Products Configuration Wizard on each machine in the farm. If you prefer to run the command line version psconfig.exe ensure to have a look here for the correct options.

Please ensure to have a look at the SharePoint Patching Best Practices before applying new fixes.

  1. Hello, Stefan! We applied uber-subscription-kb5002474.exe on all our servers. However, one server is reporting “… (KB5002474) … Missing/Required” under “Microsoft SharePoint Server Subscription Edition 1033 Language Pack”

    KB5002474 is “Installed” under “SharePoint Server Subscription Edition Core”

    We can’t reinstall the same uber patch. It says “There are no products affected by this package installed on this system.”

    What’s the best way to resolve? Is there a separate wssloc patch?

    Thanks for the response.


    1. Hi Allan,
      the error indicates that the information about the installed update has not been updated in the Config Database.
      To fix this run the following command in the SharePoint Management Shell:

      Get-SPProduct -local

      This will scan the local machine for installed fixes and update the information in the configuration database.


      1. I checked Central Admin before executing the command. Seems like it resolved overnight.

        But I’m keeping this command in my bag of tricks. I thought, I’d have to uninstall and reinstall.

        Thank you for the quick response.
