Concise Instructions

$Session = New-PSSession -ConfigurationName Microsoft.Exchange -ConnectionUri https://outlook.office365.com/powershell-liveid/ -Credential $UserCredential -Authentication Basic -AllowRedirection

Import the session. You should see the standard PowerShell progress bar as the commands are imported:

Import-PSSession $Session

Get-UnifiedGroup -Identity [email protected] | FL EmailAddresses

Set-UnifiedGroup -Identity [email protected] -EmailAddresses @{Add="[email protected]"}
