    This error started to appear at version >= 3.7.0 Remove the version you have installed and try with version 3.6.0

    Uninstall-Module ExchangeOnlineManagement

    I started getting the same error after upgrading the module from version 3.1.0 to version 3.7.1.

    That error only happens when I launch PowerShell (Admin) or with admin permission. I manage to connect to Exchange Online Management without errors when I use PowerShell with a non admin account (regular user account).

    I didn't uninstall/reinstall the module. Just close PowerShell (Admin) and launch PowerShell. Yes I'm still using module v3.7.1.

    Hi, @Andrea Thiel

    Based on your description, this looks like you're getting an error when connecting to Exchange Online PowerShell using the interactive interface.

    Here are some suggestions you can follow:

    1.Make sure you have installed the Exchange Online management module: 

    Install-Module -Name ExchangeOnlineManagement

    2.Use the following command to log in: 

    Connect-ExchangeOnline -UserPrincipalName [email protected] -ShowProgress $true

    More information can be found Connect to Exchange Online PowerShell | Microsoft Learn

    3.How did you get the token? See microsoft graph api - Could not login using access token from powershell - Stack Overflow

    4.If your organisation uses federation and your identity provider (IDP) and/or Security Token Service (STS) aren't publicly available, you can't use a federated account to connect to Exchange Online PowerShell.

    5.Make sure your root certificate is the latest certificate from a trusted authority. If you're using a self-signed certificate or a certificate from an internal CA, you need to trust that CA. You can import CA certificates into a trusted root certificate store.

    6.Enable TLS 1.2.

    7.Log in with a different administrator account to see if the problem persists.

    If an error occurs in the above steps, you can also attach a screenshot.
