Fix: “Connect-SPOService: No valid OAuth 2.0 authentication session exists” Error
Problem:
When trying to connect to SharePoint Online through PowerShell 7, got this error message “Connect-SPOService: No valid OAuth 2.0 authentication session exists”.
Solution:
Use the “-UseWindowsPowerShell” switch to import the PowerShell Module for SharePoint Online, when you use PowerShell 7!
Import-Module Microsoft.Online.SharePoint.PowerShell -UseWindowsPowerShell
