any advice?

I also explicitly added TLS1.2 before calling the .exe as follow:-

Show-Message -Message "Step 1a: Create groups and adding users to it"
[Net.ServicePointManager]::SecurityProtocol = [Net.SecurityProtocolType]::Tls12
& " $HelperPath\Microsoft.Legal.MatterCenter.CreateGroups.exe" "true" $Username $Password

but still i am getting the exact same error Message: The underlying connection was closed: An unexpected error occurred on a send... Any one has any idea how to fix this error? Thanks

Hi @john john ,
If you are using .Net 4.0. TLS 1.2 is not supported, but if you have .NET 4.5 (or above) installed on the system then you still can opt in for TLS 1.2 even if your application framework doesn’t support it. The only problem is that SecurityProtocolType in .NET 4.0 doesn’t have an entry for TLS1.2, so we’d have to use a numerical representation of this enum value:

[Net.ServicePointManager]::SecurityProtocol =  [Enum]::ToObject([Net.SecurityProtocolType], 3072)
