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”.

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

  • The same error message “No valid OAuth 2.0 authentication session exists” appears if the environment is in ITAR. Make sure to add -Region ITAR when running Connect-SPOService.

    Example: Connect-SPOService -url “https://salaudeen-admin.sharepoint.com” -Region ITAR

    where https://salaudeen-admin.sharepoint.com is the admin URL of an ITAR tenant

  • It doesn’t work on the inbuilt Windows 10 PowerShell version 5. You can check the version by using this command.
    $PSVersiontable

    The “-UseWindowsPowerShell” does work if you install PowershellVersion 7 and then make sure you are using the correct version becasue they will install side by side.
    “C:\Program Files\PowerShell\7\pwsh.exe”

    I still get the error though!

    I’m not sure, there may be a tanant setting that needs to be changed.
    I do have MFA enforced
