Description of the security update for SharePoint Enterprise Server 2016: June 9, 2020

Applies to: SharePoint Server 2016

Improvements and fixes


This security update contains fixes for the following nonsecurity issues:
  • A profile synchronization timer job does not sync integer-mapped user properties that have a User Information list. 
  • Creating a site master fails if multiple authentication methods are used for the web application.
  • Regional settings are incorrect for the Santiago (Chile) time zone.

    Note To fix this issue completely, you have to install KB 4484344 together with this update.
  • The SPFx Web Part app can be removed at the second stage recycle bin. Even if the same Web Part app is still available in the site, the removal causes a Web Part app error.

    Note To fix this issue completely, you have to install KB 4484344 together with this update.
  • A profile sync failure occurs if users configure the Active Directory (AD) import profile sync connection to use port 636 (LDAPS) instead of port 389.
