Hi
I have tested Connect-ExchangeOnline on an integration platform and it works perfectly
But when I test the same command on my production platform I get the following error :
Connect-ExchangeOnline -Credential $MyCredential -Prefix "M365"
Impossible de charger le fichier ou l'assembly 'System.Net.Http, Version=4.2.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' ou une de ses dépendances. Le fichier spécifié est introuvable.
Au caractère C:\Program Files\WindowsPowerShell\Modules\ExchangeOnlineManagement\3.0.0\netFramework\ExchangeOnlineManagement.psm1:726 : 21
What's the problem on this platform ?

Hi @Valérie Bauche ,
As Andy has replied above, you could follow the Andy's suggestion to upgrade the .NET and check if this issue continues.
If upgrading .NET cannot resolve your issue, you could try below command to check if it connects to exchange online:
Connect-ExchangeOnline -UserPrincipalName user@contoso.onmicrosoft.com
For more details: Connect to Exchange Online PowerShell
In addition, I want to confirm with you if there are any error messages related with the issue in event logs?

I have updated my EXO v2 to V3 and got this error. Current version of .NET is 4.5 How can I resolve this?
I would upgrade to .net 4.8 and try again
