Hi AndreyLutsenko-0673,
You will need to download and install the more up to date Group Policy Administrative Templates (ADMX) to manage Microsoft Office 2019 settings:
https://www.microsoft.com/en-us/download/details.aspx?id=49030
Extract the downloaded GPO template file. The archive contains:
The admin directory – contains a set of OPAX/OPAL files to configure Office deployment options using the Office Customization Tool (OCT). In our case this folder is not used;
The admx directory – contains a set of ADMX and ADML files for the Group Policy Editor;
office2016grouppolicyandoctsettings.xlsx file – Excel file with the description of all Group Policies and matches between GPO options and registry keys for Office apps. This XLSX file can be used as a reference for the available Office Group Policy options.
I hope this answers your question.
