Connecting to Exchange Online with PowerShell

This article explains how to connect to Exchange Online with PowerShell.

Prerequisites

You need to be a Global Administrator in the Office 365 Tenant, or at the least be assigned to the Exchange Administrator role.

You need to be using a 64-bit version of one of the following Windows OS:

  • Windows 10
  • Windows 8 or 8.1
  • Windows 7 SP1
  • Windows Server 2016
  • Windows Server 2012 R2
  • Windows Server 2012
  • Windows Server 2008 R2 SP1

You need to install Microsoft .NET Framework 4.5.x, and either Windows Management Framework 3.0 or 4.0.

The following modules are required:

Configure PowerShell to run signed scripts for Exchange Online.  Run the following in an elevated PowerShell session:

Set-ExecutionPolicy RemoteSigned

Connect to Exchange Online

Create a PowerShell credentials object:

$credential = Get-Credential

SfBOnlineConnect1

A dialog box will appear to enter your credentials. Enter your username and password, then click OK.

Run the following command:

$exchangeSession = New-PSSession -ConfigurationName Microsoft.Exchange -ConnectionUri https://outlook.office365.com/powershell-liveid -Credential $credential -Authentication “Basic” -AllowRedirection

Although a connection has been established to Office 365, it’s necessary to run the following command to download scripts, cmdlets, etc. to manage Exchange Online:

Import-PSSession $exchangeSession -DisableNameChecking

ExOnline

Close the Connection

When you’re done, closing the PowerShell window will leave the remote connection to Exchange Online active for the next 15 minutes. It’s good practice to end the session when you’re done.

Remove-PSSession $exchangeSession
