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.

Hello,

in my case BitDefender block the request.

With an antivirus exception all work fine. ;)

Bye.

@Ron-6928 I can't believe the answer was so simple. Since moving from AD/hybrid to Entra joined, I have not been able to connect to Exchange Online. Never thought to not run PS as admin as it was just instinctive. Running as standard user worked for me.

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
Install-Module -Name ExchangeOnlineManagement -RequiredVersion 3.6.0
Get-InstalledModule ExchangeOnlineManagement

This resolved the issue for me. I laughed when I read the intro message "You’re currently using an older version and we recommend upgrading to V3.7 for enhanced performance."

I rather use an older version that works, versus using a newer version that provides "enhanced performance" while not working properly.

This worked for me.

I found that v3.7.1 worked as long as you didn't run PowerShell as an admin or another user. However, Connect-ExchangeOnline with my admin account fails if the PowerShell is not running under the same account.

I'd just like to add if Uninstall-Module doesn't work, then you can remove the modules manually from C:\ProgramFiles\WindowsPowerShell\Modules\ExchangeOnlineManagement, and then delete the newer version folder. Re-install again on Powershell with the earlier version. This worked for me.

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.

Lots of people have this problem with ExchangeOnlineManagement 3.7.0. I have not had time to investigating the actual cause of this error yet. I went for the most common workaround for now which is to downgrade to 3.6.0;

Install-Module -Name ExchangeOnlineManagement -RequiredVersion 3.6.0
