Introduction

How to install Zivver Office Plugin via Group Policy Objects (GPO) for Microsoft Windows.

Minimal technical requirements

System requirements

• Microsoft Windows 7 Extended Security Updates or higher.
• Microsoft .NET Framework 4.8 or higher.
• Microsoft Outlook 2013 or higher.
• Memory utilization: +/- 150 MB in total per Outlook session.

Product specific requirements

• HTTPS connection, port 443, TLS v1.2 or higher with https://*.zivver.com.
• Outlook in Cached Mode(1).
• A Microsoft supported scenario when using different versions of Office, Project, and Visio on the same computer.

(1) Zivver follows the recommended practice of Microsoft and Citrix for optimal performance with Outlook in Cached Mode. Performance issues related to Online Mode will be investigated on a best-effort basis.

GPO specific requirements

• Administrator rights in Microsoft Active Directory (AD) to create and deploy new GPOs, for example Domain Administrator.
  

  If you are a member of the Group Policy Creator Owners group, you can create and edit GPOs, but you cannot assign them to AD groups or users.

• Access to a domain controller (DC), for example via Remote Desktop Protocol (RDP) or the Remote Server Administration Tools.

• Optional - Access to these:

  • Recommended: Access to a DC’s SYSVOL folder to install the ADM files in the domain’s GPO Central Store, so that they are replicated across the entire domain, and can be managed from other domain servers.
  • Alternatively: If you do not use the Central Store, the ADM files can be installed locally on a DC. The downside to this option is that the ADM files will not be available automatically on other domain servers, and can only be managed on this server.

   • Assigning on user level installs the plugin on user login.
   • Publishing makes the plugin available for users to install from the Add and remove programs pane in Control panel.

Recommended Office plugin settings

This chapter explains how to install and configure the recommended Office plugin settings. The settings are configured in a GPO, and can be deployed to users or systems within an AD domain, or implemented locally on standalone systems (without AD).

You need the following ADMX and ADML files (ADM files in short) to configure the settings in a Group policy.

• Download ADMX file
• Download ADML file

Install the ADM files

The ADM files can be installed in three ways:

1. Recommended - Central Store installment
   Installing the ADM files in the Central Store allows you to replicate the Office plugin settings to others servers within the domain.
2. Local domain server installment
   Installing the ADM files on a local domain server allows you to deploy the Office plugin settings to other servers, but in contrast to the Central Store installment the files are not automatically replicated to other servers.
3. Standalone system (without AD) installment
   Installing the ADM files on a standalone system allows you to deploy the Office plugin settings on a machine, so that you don’t have to make changes in the registry manually.

Central Store installment

1. Connect to one of your DC’s with administrator rights.
2. Open File Explorer.
3. Access the Central Store in the SYSTOLE share: %LogonServer%\SYSVOL\%UserDnsDomain%\Policies\PolicyDefinitions.
   For example \\Zivver_Server\SYSVOL\Zivver.local\Policies\PolicyDefinitions.
4. Put the ADMX file in the folder %LogonServer%\SYSVOL\%UserDnsDomain%\Policies\PolicyDefinitions.
5. Put the ADML file in the folder %LogonServer%\SYSVOL\%UserDnsDomain%\Policies\PolicyDefinitions\en-US.
   The AMD files are now installed in the Central Store and should be available as Zivver Office Plugin Settings under Policies > Administrative Templates in the Group Policy Management Editor.
   

Local domain server installment

1. Log in on a domain server with administrator rights.
2. Open File Explorer.
3. Access following folder: %WinDir%\PolicyDefinitions.
   For example C:\Windows\PolicyDefinitions.
4. Put the ADMX file in the folder %WinDir%\PolicyDefinitions.
5. Put the ADML file in the folder %WinDir%\PolicyDefinitions\en-US.
   The AMD files are now installed in the Central Store and should be available as Zivver Office Plugin Settings under Policies > Administrative Templates in the Group Policy Management Editor.
   

Standalone system (without AD) installment

1. Log in on the system with administrator rights.
2. Open File Explorer.
3. Access following folder: %WinDir%\PolicyDefinitions.
   For example, C:\Windows\PolicyDefinitions.
4. Put the ADMX file in the folder %WinDir%\PolicyDefinitions.
5. Put the ADML file in the folder %WinDir%\PolicyDefinitions\en-US.
   The AMD files are now installed in the Central Store and should be available as Zivver Office Plugin Settings under Policies > Administrative Templates in the Group Policy Management Editor.
