In my previous post, I talked about setting up DKIM DNS for Office 365. However, you need PowerShell to log into the ExchangeOnlineManagement system.
In simplest forms, PowerShell is a cross-platform shell and scripting language that allows people to manage tasks from the command line and automate thousands of activities. Moreover, it’s a language built on Microsoft’s .NET Framework that makes our lives easier.
Wikipedia describes its functionality as:
Administrative tasks are performed by cmdlets (pronounced command-lets). Cmdlets are are specialized .NET classes implementing a particular operation. They access data in different data stores, like the file system or registry, which are made available to PowerShell via providers. Third-party developers can add cmdlets and providers to PowerShell. Cmdlets are used by scripts, which can be packaged into modules.
In this post, I’ll do a short breakdown of how I did it. In addition for more detailed information, visit the Microsoft documentation.
Install PowerShell
Since I work on a Mac, I usually install software through Homebrew. PowerShell is no different.
Fire up your terminal and install it.
$ brew install --cask powershell

PS /Users/michael> Import-Module ExchangeOnlineManagement
Import-Module: The specified module 'ExchangeOnlineManagement' was not loaded because no valid module file was found in any module directory.It doesn’t come with a pre-installed set of modules for the Microsoft Office stack. So you actually have to separately install the ExhangeOnlineManagement module.

You are installing the modules from an untrusted repository. If you trust this repository, change its InstallationPolicy value by running the

| system.During my search on the net, I learned you have to install the PSWSMan module and WSMAN.
Exit and return to your terminal prompt. The reason to install the modules outside of PowerShell is that you will need to restart it anyway in order for WSMan to take effect.
$ pwsh -Command 'Install-Module -Name PSWSMan'
$ sudo pwsh -Command 'Install-WSMan'
