Improvements and fixes

Customers using Access Services must take additional actions for the feature to continue to work and remain supported.

The Access Services feature in SharePoint Server 2016 has dependencies on certain SQL Server 2012 components that are no longer supported with SharePoint Server 2016. This security update includes changes to the Access Services feature that enable it to be compatible with newer SQL Server components. To make sure that the Access Services feature continues to work and remains supported, Access Services customers should upgrade the following components before they install this security update for SharePoint Server 2016. (These components can also be upgraded after this security update for SharePoint Server 2016 is installed. However, the Access Services feature might no longer work until the components are upgraded.)

After this security update for SharePoint Server 2016 is installed, Microsoft recommends that you uninstall the following SQL Server component from your SharePoint Server 2016 virtual machines because it is no longer used by or supported with Access Services.

  • Microsoft SQL Server 2012 Native Client (sqlncli.msi)
