This article describes update 4484215 for Microsoft SharePoint Enterprise Server 2016 that was released on January 14, 2020.

Improvements and fixes

This update improves the compliance level of cookies that are generated by a SharePoint search.

This update also fixes the following issues in SharePoint Server 2016:

  • You are unable to access Office Add-Ins from a document that is opened in a browser when they are provided by the SharePoint App Catalog Service.

  • When you log into SharePoint by using multiple authentication types at the same time such as a SAML token and a FedAuth cookie, the URL redirection happens to the root of the web application instead of the actual resource.

  • Fixes an issue in the SharePoint eDiscovery Center portal where errors are produced when you export content from a site preservation hold library.

  • When you create a new document in Word and try to save it to a document library with a content type that has required properties, you are blocked from saving because the Document Information Panel doesn't show required properties.

  • Calendar overlay items that are listed under Calendars in View are not clickable.

This update also fixes the following issues in Project Server 2016:

  • Fixes performance problems when you perform actions such as connecting Project to the server, trying to see a list of projects from the server, going to the Project Center page and so on.

  • When the Schedule Variance Percentage (SVP) or Cost Variance Percentage (CVP) earned value becomes very large, this causes an overflow condition. It causes the client-side object model (CSOM) or REST calls to fail when you access the project. The SVP and CVP values now have a lower limit of "-100%" and upper limit of "100%".
