Connect-Exchange Online (Error while sending the request)

Question

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

Any steps to solve this issue?

Answer 2

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.
