EOP / Office 365: Connect and Use Powershell

The blog will explain the steps on how to connect to office 365 or Exchange online protection for the management using powershell of your desktop client computer.

Connecting Steps:

  1. Open powershell with Run as Administrator on your computer


  2. Run the command to cache authentication

    $Cred = Get-credential


    This will popup authentication windows. Type your login id which is the User principal name and password.


  3. Run the command to configure the powershell to use the office 365.

    $Session = New-PSSession -ConfigurationName Microsoft.Exchange -ConnectionUri -Credential $Cred -Authentication Basic –AllowRedirection


  4. Verify and change the execution policy.


    To verify run the command:



    To change run the cmd

    Set-ExecutionPolicy RemoteSigned


         5. Run the below command to import the session
        Import-PSSession $Session


If your executionpolicy will be Restricted then you will see the below error:

Import-PSSession : Files cannot be loaded because the running of scripts is disabled on this system. Please provide a

valid certificate with which to sign the files.


           6. Now your powershell is ready to use and run any command here.

As an example I ran the below command





Disconnecting Session


Run the below command to disconnect the session:

Remove-PSSession $Session



To verify run the working command as mentioned below and you will see the below error

Command: Get-Mailbox

Error: The term ‘Get-Mailbox’ is not recognized as the name of a cmdlet, function, script file, or operable program. Check the spelling of the name, or if a path was included, verify that the path is correct and try again.

    I have successfully connect to Office 365 using Windows Azure Active Directory Module for Windows PowerShell. I can also run many commands, such as Get-MsolUser. However I still have problem that the power shell not recognize the commands “Set-TransportConfig -AddressBookRoutingEnabled $true”

    I would appreciate if any one can advise how to resolve this issue?

    Thank you

    You need to connect to exchange module in other words office 365 module. Azure module is different.
