Microsoft Office Patchday (December 3, 2019)

[German]On December 3, 2019 (the first Tuesday of the month, Office Patchday), Microsoft released a series of non-security updates for versions of Microsoft Office (this time Office 2016 only) that are still supported.


The updates apply to the installable MSI version of Office and are made available through Windows Update. Click-to-run packages receive updates through other channels. For this reason, Office 2019 no longer appears in the following list because only click-to-run installers are available. Microsoft lists the updates on this page.

Office 2016

The packages are automatically distributed via Windows Update, but can also be manually downloaded and installed via the linked KB articles.

  • Update for Microsoft Office 2016 (KB4484170): Fix for an issue with server connections. When you connect Microsoft Project online to Project Server, you receive the following error message: "The server that you want to access is using an authentication protocol that is not supported by this version of Office." This update fixes the problem. After you install this update, you can successfully log back on to Project.
  • Update for Microsoft Outlook 2016 (KB4484172): If the Brasilia time zone was used in 2019, recurring meetings and appointments for 2020 appear in the wrong time window. This update is relevant to Outlook if Brasilia's time zone is set, or for meetings and appointments that are set in that time zone. This update allows Outlook to override certain time zone settings that are used by Outlook. To override a time zone, you must set a registry key for the current user. The registration key is listed in the linked support article.
  • Update for Skype for Business 2016 (KB4484133):  Increases the version number of the Microsoft Skype for Business 2016 client to 16.0.4939.1000. In addition to releasing the new client, this update includes stability and performance improvements. Before you install this update, please review the requirements in the support article.

There were no updates for older versions of Office. The fixes for the click-to-run versions – including the access bug – will probably be released on December 10, 2019.
