February 2021 CU for SharePoint Server 2016 is available for download

The product group released the February 2021 Cumulative Update for SharePoint Server 2016 product family.

This CU also includes Feature Pack 1 which was released with December 2016 CU and Feature Pack 2 which was released with September 2017 CU.

The KB articles for February 2021 CU are available here:

  • KB 4493195 – February 2021 Update for SharePoint Server 2016 (language independent) – This is also a security update!
  • There was no language dependent fix released this month. The most recent language dependent fix is KB 4493167 from January 2021 CU

The download for February 2021 CU is available here:

Important: It is required to install both fixes (language dependent and independent) to fully patch a SharePoint server. This applies also to servers which do not have language packs installed. The reason is that each SharePoint installation includes a language dependent component together with a language independent component. If additional language packs are added later (only) the language dependent fix has to be applied again.

It is irrelevant which language you pick on the drop down in download center. Even the language dependent fixes are all in the same package for all languages.

After installing the fixes you need to run the SharePoint 2016 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.

SharePoint 2016 February 2021 CU Build Numbers:

Language independent fix: 16.0.5122.1000

To understand the different version numbers please have a look at my article which explains the different SharePoint build numbers.

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

    1. Hi Henry,
      yes, both issues are fixed in this CU. The fix for the 100 MB issue was already included in December 2020 and January 2021 CU.
      Cheers,
      Stefan

  2. Hi Stefen,

    we have already installed Jan 2021 CU and for Feb 2021 CU there is no language dependent fix released this month, so if we want to install this month(FEB 2021) CU then we need to install only language independent right?

    Thanks
    Praveen

    1. Hi Praveen,
      yes – if you already installed the Jan 2021 CUs language dependent fix you only have to install the language independent one released in February.
      Cheers,
      Stefan

  3. Hello Stefan, we haven’t installed the January CU yet and would actually install the February CU directly. Then we wouldn’t have a language-dependent update.

    Do we need to apply both January updates or can we apply the February language-independent update with the January language-dependent update?

    Can you recommend us for this?

    Regards
    Christian

    1. Hi Christian,
      in this case you only need to install the language independent fix from February and the language dependent fix from January.
      Cheers,
      Stefan

    Is there a sequence to consider?

  5. The February CU has a documented issue if you have the Document ID Feature enabled….links broken in the document panel ellipse for the link to document. In our lab we have determined this is the case. Any idea when they will have fix for this…the workaround just isn’t user friendly for users? Can’t apply CU tell a fix available.

    1. Hi Allen,

      the current plan is to release a fix with March CU.

      Cheers,
      Stefan
