Microsoft Exchange Online Powershell Module:

You will need a Windows machine with the latest version of Powershell. You will need to specifically install Exchange Online Powershell with MFA Support. This can be downloaded from
https://docs.microsoft.com/en-us/powershell/exchange/exchange-online/connect-to-exchange-online-powershell/mfa-connect-to-exchange-online-powershell?view=exchange-ps

OR

https://cmdletpswmodule.blob.core.windows.net/exopsmodule/Microsoft.Online.CSE.PSModule.Client.application
 (you may have to download in IE/Edge)

When running these Powershell scripts you will see a message along the lines of “WARNING: The names of…” – this is an issue with Microsoft not documenting their Official Powershell scripts well enough! But it is not an issue to worry about.

#Import the right Exchange Online module to talk with Azure AD
Import-Module $((Get-ChildItem -Path $($env:LOCALAPPDATA+"\Apps\2.0\") -Filter Microsoft.Exchange.Management.ExoPowershellModule.dll -Recurse ).FullName|?{$_ -notmatch "_none_"}|select -First 1)

#Auth to the tenant and setup powershell
$ExoSession = New-ExoPSSession
Import-PSSession $ExoSession -AllowClobber
