A new cumulative update (January 2023 CU) has been released for SharePoint Server 2016.

This CU includes both Feature Pack 2, available since the September CU (September 2017 CU), and the earlier Feature Pack 1.

SP Build:
16.0.5378.1000 (Language independent CU)

SharePoint 2016 CU – KB articles describing the CU:

  • KB 5002338 – January 2023 Update for SharePoint Server 2016 (language independent)
  • No new language-dependent package was released for this CU. Use the latest available language CU: KB 5002289 (November 2022 CU).

SharePoint Server 2016 CU – CU download links:

After installation, remember to run the SharePoint 2016 Products Configuration Wizard or the following command:

PSConfig.exe -cmd upgrade -inplace b2b -wait -cmd applicationcontent -install -cmd installfeatures -cmd secureresources -cmd services -install

Important notes

Always install both packages in this order:

  1. language independent components (core CU for this release)
  2. language-dependent components (latest available language CU: KB 5002289, November 2022 CU)

For language-dependent packages, the language you select does not matter because each package contains updates for all languages.

If you install a new language pack on a SharePoint Server 2016 farm, you must reinstall the language-dependent update afterwards.

Remember to keep Distributed Cache updated as well as SharePoint. See How to update Distributed Cache correctly (in Czech).

Note for this CU:

KB5002338 requires the release version of SharePoint Enterprise Server 2016.

Enabling the modern OneDrive for Business experience requires an active Software Assurance contract, whether enabled by this update or manually. Without an active contract at enablement, disable this experience.

After KB5002338, a SharePoint site may become inaccessible when its URL contains a blocked file extension. See KB5023406.
