Connect to Office 365 Powershell

After Powershell has been installed, it’s very easy to connect to Office 365. Open the Powershell terminal and type the following (First step will ask for O365 admin credentials)

$O365Credential = Get-Credential

$Session = New-PSSession -ConfigurationName Microsoft.Exchange -ConnectionUri https://outlook.office365.com/powershell-liveid/ -Credential $O365Credential -Authentication Basic -AllowRedirection

Import-PSSession -Session $Session

The last step takes a few seconds until the Office 365 session has been imported. Afterwards you can run the available Powershell cmdlets.
