Hello,
I'm getting the below Error while connecting to Exchange Online (PowerShell Script) when called from .Net Application.
#Import-Module ExchangeOnlineManagement
#Connect-ExchangeOnline -Credential $Creds
An error occurred while sending the request.
At C:\Program
Files\WindowsPowerShell\Modules\ExchangeOnlineManagement\3.4.0\netFramework\ExchangeOnlineManagement.psm1:762 char:21
+ throw $_.Exception.InnerException;
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ CategoryInfo : OperationStopped: (:) [], HttpRequestException
+ FullyQualifiedErrorId : An error occurred while sending the request.
I've checked the Credentials. Updated the Exchange Online Module. Checked .Net Framework and its Compatible.
I'm using Windows PowerShell 5.1.
Policy is been set to Bypass.
Thanks & Regards

Is there a problem if you connect EXO without the .net application?

Russ S 20 Reputation points2024-03-05T22:39:38.7833333+00:00 I had the same issue, but was able to solve it by specifying Tls 1.2.
Add this line:
[Net.ServicePointManager]::SecurityProtocol = [Net.SecurityProtocolType]::Tls12
That should get you past that error.

Andre g 6 Reputation points2024-05-13T12:15:06.99+00:00 We tried with registry keys for TLS, with latest updates for Exchange and Windows server.
The error was fixed temporarely, but now is back in all machines behind our customer network. So I just updated the Sonicwall, but the error persists.

2024-06-03T19:48:04.0966667+00:00 Try this line before connect
[Net.ServicePointManager]::SecurityProtocol = [Net.SecurityProtocolType]::Tls12 -

2024-06-03T20:23:15.97+00:00 I have this line in the script before the Connect-ExchangeOnline command. Unfortunately the error is the same.

2024-06-03T20:37:50.33+00:00 It was the firewall Content Filtering feature in our case, so we fixed by creating an exclusion for the internal machines doing Connect-exchangeonline. Some Microsoft servers are blacklisted in Sonicwall.
