If you use PowerShell to connect to Office 365 services, and also have MFA enabled, you already know there is always some issue to connect with PowerShell to some of the Office 365 services.

To do so, you need to download and install the Exchange Online PowerShell module from the Exchange Online ECP- Hybrid section
