Concise Instructions
Open PowerShell.
Allow Remote, Signed scripts so you can import Microsoft O365 Exchange commands. We will set this back to default when done:
<pre><code class="lang-auto">Set-ExecutionPolicy RemoteSigned

</code></pre>
Enter your credentials so you can manage the O365 environment you are working on. It will prompt you for your username and your password:
<pre><code class="lang-auto">$UserCredential = Get-Credential

</code></pre>
Create a new PowerShell session to import the Microsoft O365 Exchange commands:
<pre><code class="lang-auto">$Session = New-PSSession -ConfigurationName Microsoft.Exchange -ConnectionUri https://outlook.office365.com/powershell-liveid/ -Credential $UserCredential -Authentication Basic -AllowRedirection

</code></pre>
Import the session. You should see the standard PowerShell progress bar as the commands are imported:
<pre><code class="lang-auto">Import-PSSession $Session

</code></pre>
Now you are ready to issue your commands. First, make sure you can read the properties of the Exchange Group:
<pre><code class="lang-auto">Get-UnifiedGroup -Identity humanresources@contoso.com | FL EmailAddresses

</code></pre>
It should output the aliases assigned to the Outlook Group.
To add the alias, enter this command. I will use my example in the question above to show what it looks like:
<pre><code class="lang-auto">Set-UnifiedGroup -Identity humanresources@contoso.com -EmailAddresses @{Add="jobs@contoso.com"}

</code></pre>
You can then run the <code>Get-UnifiedGroup</code> command and see the alias now listed in the email addresses.
Return to the default execution policy:
<pre><code class="lang-auto">Set-ExecutionPolicy Default

</code></pre>
Next Steps
At this point the group has an alias. You can email the alias internally to your O365 account. For instance, <a href="mailto:User1@contoso.com">User1@contoso.com</a> can email <a href="mailto:jobs@contoso.com">jobs@contoso.com</a> and it will work correctly. It will be
