Overview
This guide explains the steps required to deploy Workplace Chat application via Windows installer (or .msi package). .msi is an installer package file format used by Windows for installation, storage, and deletion of programs. The files are stored within a package, which is then used with the program’s client-side installer service to open and install the program.
The system administrator of a company will typically deploy .msi packages via the Windows Server group policies objects (GPO) or through a third party software deployment tool.
The main idea is that an application will be automatically installed the next time a user logs in to their computer. This means that the application will automatically be installed without the need for an end-user, who might not have permissions to install applications, to run the executable manually.
Deploy Workplace Chat MSI by using group policies (GPO)
In order to deploy Workplace Chat MSI by using group policy objects, follow the steps below:
.msi to a shared folder so that the installer can be deployed over the network.
.msi and click on Open. 
gpupdate /force to update the group policies.
Workplace Chat MSI deployment features
Workplace Chat .msi deployment follows a sequence of steps:
.msi is running by some provisioning system across many PCs), then run with "START=N". E.g.: msiexec /i WorkplaceChat.msi START=Nmsiexec /i WorkplaceChat.msi INSTALLEROPTS="/S" which runs the installer in silent mode.Troubleshooting
When you want to deploy an .msi, you can use the .msiexec to run a couple of commands in a terminal prior to deploying the .msi in the group policies or third party deployment tool. The msiexec has the possibility to run install, display, restart and most importantly logging options.
