# Office Plugin Installation Manual for Microsoft Configuration Manager

## Introduction
How to install the Zivver Office Plugin with Microsoft Configuration Manager.

## Minimal technical requirements

### System requirements
- Microsoft Windows 10 or higher.
- Microsoft .NET Framework 4.8 or higher.
- Microsoft Outlook 2021 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 Mode1.
- A [Microsoft supported scenario](https://docs.microsoft.com/en-gb/DeployOffice/install-different-office-visio-and-project-versions-on-the-same-computer?toc=/deployoffice/office2019/toc.json#example-installation-scenarios) when using different versions of Office, Project, and Visio on the same computer.

1) Zivver follows the recommended practice of [Microsoft](https://support.microsoft.com/en-us/office/turn-on-cached-exchange-mode-7885af08-9a60-4ec3-850a-e221c1ed0c1c) and [Citrix](https://docs.citrix.com/en-us/tech-zone/build/deployment-guides/microsoft-365-citrix.html) for optimal performance with Outlook in Cached Mode. Performance issues related to Online Mode will be investigated on a best-effort basis.

### Microsoft Configuration Manager specific requirements
- Access to Microsoft Configuration Manager, with the following permissions:
  - **Application Administrator Security Role**, to create, modify, and deploy applications.
  - **Compliance Settings Manager Security Role**, to create, modify, and deploy configuration items.
  - Having access to the **Full Administrator** or **Operations Administrator** Security Roles will also work, but these roles provide additional privileges that are not necessary.

## Installation
This chapter explains how to install and deploy the Zivver Office Plugin via Microsoft Configuration Manager.

Note

Configure the [Recommended additional settings](https://docs.zivver.com/en/admin/officeplugin/microsoft-configuration-manager-installation-manual.html#recommended-additional-settings) described in this manual. With these recommended settings you ensure users will always be able to send secure emails.

### Share the plugin
The plugin must be available on the network for it to be deployed via Microsoft Configuration Manager. Follow these steps to create a distribution point on the server.
1. Log in on a domain server as administrator.
2. Create a new shared network folder or select an existing one.
3. Put the Office plugin installer package in this folder.

[Download the latest version](https://downloads.zivver.com/officeplugin/latest/Zivver.OfficePlugin.Installer.msi)
4. Make sure the package can be accessed.
_Change the permissions on the shared folder if necessary. The plugin should now be available for installation from the shared network folder._

### Create an application
The plugin can be configured in Microsoft Configuration Manager as a package or an application. In this manual, you will deploy the plugin as an application. The benefit of deploying the plugin as an application is that this allows for easier updates with the **Supersedence** feature.

Follow these steps to create a new **Application** for the plugin in Microsoft Configuration Manager.
01. Go to **Software Library**.
02. Expand the **Application Management** folder.
03. Select **Applications**.
04. Right-click and select **Folder > Create Folder** to create a new folder for the plugin. Choose the location based on how folders are organized in your organization’s tree structure.
05. Give the new folder a name.
    _For example Zivver Office Plugin._
06. Click **OK** to confirm.
07. Right-click the folder you just created and select **Create Application**.
08. Choose the option to **Automatically detect information about this application from installation files**.
09. In the **General** tab of the **Create Application Wizard**, click **Browse...**.
10. Select the MSI package of the plugin in the network share, that was configured at [Share the plugin](https://docs.zivver.com/en/admin/officeplugin/microsoft-configuration-manager-installation-manual.html#share-the-plugin), and click **Open**.
11. As the **Installation File Type**, select **Windows Installer (.MSI file)** if this is not automatically specified already.
12. Click **Next**.
13. Click **Next** again.
14. In the **General Information** tab, enter additional information about the application:
    - Change the **Name** if you prefer.
    - Enter any optional **Administrator comments**.
    - Change **Publisher** to `Zivver B.V.`.
    - Add **Administrative Categories** if you prefer, depending on internal organizational standards.
      _This might help to filter and categorize the application._
    - The default command next to **Installation Program** should be fine, but consider the following:
      - Add the parameter `/q` for a silent install if it is not specified already.
      - Add `REBOOT=REALLYSUPPRESS` so that the systems will not be rebooted.
      - Add `/L*V %FileLocation%` if you want to create a verbose log of the installation process.
  - Add `ALLUSERS=1 USEIMPERSONATE=0` to install the plug-in for all the users.
  - Select one of three options for the **Install Behavior**. The options are as follows:
    - **Install for user** - The client installs the application only for the specific user accounts to which you deploy it, rather than for all users on the device.
    - **Install for system** - The client installs the application only once. It’s available to all users.
    - **Install for system if resource is device; otherwise, install for user** - If you deploy the application to a device, the client installs it for all users. If you deploy the application to a user, the client only installs it for that user.
15. Click **Next**.
16. Verify the information in the **Summary** pane and click **Next** again.
    _Wait a moment until the application is created._
17. Click **Close** to exit the application wizard.
    _The new application will now be listed in the Zivver Office Plugin application folder._

#### Configure the application properties
Configuring additional properties is optional. Follow these steps to configure additional properties of the application that you created in the previous section.
1. Go to **Software Library**.
2. Right-click the **Zivver Office Plugin** application.
3. Select **Properties**.
4. _Optional_: In the **General Information** tab, activate the option **Allow this application to be installed from the Install Application task sequence action without being deployed**.
    _This allows the application to be deployed via **Task Sequence**, for example during imaging._
5. _Optional_: In the **Application Catalog** tab, configure additional properties for the plugin based on your preference.
    _For example, if you make the plugin available in **Software Center**, users will be able to find the plugin based on this information._
6. Click **OK** to close the **Properties** window.

15. In the **Add Dependency** window, enter a name for the **Dependency Group**.
    _For example Zivver Office Plugin._
16. Click **Add...**.
17. In the **Specify Required Application** window, select your installation of **Outlook** and the related deployment type.
18. Click **OK** to confirm your selection.
19. Click **Add...** again to add another **Required Application**.
20. Select the installation of **.NET Framework v4.5+** and its deployment type.
21. Click **OK** to confirm and close the **Specify Required Application** window.
22. Choose if you want to **Auto Install** the dependencies:
    - **Auto Install on**: If the dependencies are not installed yet, they will be installed automatically before the plugin is installed.
    - **Auto Install off**: The plugin will not be installed if the dependencies are not found on the deployment target, since the requirements are not met.
23. Click **OK** to confirm and close the **Add Dependency** window.

01. Create a new **Application** for the new version of the plugin according to the steps described at section [Create an application](https://docs.zivver.com/en/admin/officeplugin/microsoft-configuration-manager-installation-manual.html#create-an-application).
02. Configure a new **Deployment Type** for the update of the plugin according to the steps described at section [Configure deployment type](https://docs.zivver.com/en/admin/officeplugin/microsoft-configuration-manager-installation-manual.html#configure-the-deployment-type).
03. Right-click the application of the plugin update.
04. Select **Properties**.
