How to fix Error Acquiring Token

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 user@example.com -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.
