Note To apply this security update, you must have the release version of Microsoft SharePoint Enterprise Server 2016 installed on the computer.

This public update delivers Feature Pack 2 for SharePoint Server 2016. Feature Pack 2 contains the following feature:

  • SharePoint Framework (SPFx)

This public update also delivers all the features that were included in Feature Pack 1 for SharePoint Server 2016, including:

  • Administrative Actions Logging
  • MinRole enhancements
  • SharePoint Custom Tiles
  • Hybrid Taxonomy

Improvements and fixes

This security update fixes an issue in SharePoint Server 2016 in which the CoauthoringVersionPeriod value is not regarded in a co-authoring session. After this update is installed, CoauthoringVersionPeriod is set to 30 minutes by default. A new version of the file won't be created automatically when a file opens in a co-authoring session. You can change the value of CoauthoringVersionPeriod per your version creation requirement.
    This security update also fixes the following issues in Project Server 2016:
    • When timesheets are submitted, the "Reporting (Timesheet Save)" queue job is created. However, this job may run very slowly. This creates a backup of queue jobs and causes other slow performance problems.
    • Project Web App instances that have many timesheets or timesheet views may experience a time-out when you create timesheet views or modify existing timesheet views. This can prevent you from creating timesheets or opening existing timesheets.

    Known issues in this update

    An error may occur when you upload a file that's larger than 100 MB to a document library.

    Microsoft is investigating this issue and will post more information in this article when a fix becomes available.

    Use one of the following methods:

    • Use the Upload button on the ribbon.
      Note You must set Allow management of content types to Yes in document library settings.
    • Use the Open with Explorer command.
      Note This option can be used to open Internet Explorer 32-bit to do file transfers.
    • Use another upload page for which the URL resembles the following: 


      • In this URL, <site_url> represents the actual URL of the webpage.

      • This method uploads the file to the root of the specific library. The file must be copied manually to the final folder structure destination.
