Sometimes you need to use Powershell to manipulate Exchange Online. When MFA is enabled, you may get something like the following error:

New-PSSession : [ps.outlook.com] Connecting to remote server ps.outlook.com failed with the following error message :Access is denied.

To fix this situation, you'll need to setup EXO V2 on your local PC. To do this:

• Make sure EXO V2 is installed on your local PC - https://docs.microsoft.com/en-us/powershell/exchange/exchange-online-powershell-v2?view=exchange-ps#install-and-maintain-the-exo-v2-module
