---

name: Bug report🐛 about: Unable to connect to exchange powershell with PowerShell.net 7.1x title: “Unable to connect to exchange powershell with PowerShell.net 7.1x” labels: Needs-Triage assignees: ‘’

---

Steps to reproduce

//Set Credential
SecureString s = new SecureString();
Config.GetValue<string>(pass).ToCharArray().ToList().ForEach(p => s.AppendChar(p));

//Use a public client app to get a OAuth token for CUBOT
var publicClientApplication = PublicClientApplicationBuilder.Create(appid).WithTenantId(Config.GetSection("AzureAd").GetValue<string>("tenantId")).Build();
var tokenworker = publicClientApplication.AcquireTokenByUsernamePassword(new string[] { "https://outlook.office365.com/.default" }, Config.GetValue<string>(user), s).ExecuteAsync();
tokenworker.Wait();

Runspace runspace = System.Management.Automation.Runspaces.RunspaceFactory.CreateRunspace();
PowerShell powershell = PowerShell.Create();
PSCommand command = new PSCommand();


s = new SecureString();
//convert the OAuth Token into a SecureString
$"Bearer {tokenworker.Result.AccessToken}".ToCharArray().ToList().ForEach(p => s.AppendChar(p));

//Create a Powershell Credential using the CUBot User and the OAuth SecureString
PSCred = new PSCredential(Config.GetValue<string>("poshuser"), s);

command.AddCommand("New-PSSession");
command.AddParameter("ConfigurationName", "Microsoft.Exchange");
//convert basic auth to modern with the query string
command.AddParameter("ConnectionUri", new Uri("https://outlook.office365.com/powershell-liveid/?BasicAuthToOAuthConversion=true"));
command.AddParameter("Credential", PSCred);
//Yes still basic auth but we are passing the OAuth token not a password
command.AddParameter("Authentication", "Basic");
command.AddParameter("AllowRedirection");
powershell.Commands = command;

runspace.Open();
powershell.Runspace = runspace;
Result = powershell.Invoke(); 

Expected behavior

successfully connects to exchange online

Actual behavior

unable to connect

Issue is in all 7.1.x builds of the SDK System.Management.Automation namespaces. This script works in 7.0.x but does not in 7.1.x

The error you get is to unable to connect to remote resource/connection closed. Again this code works in 7.0.x (inc 7.0.6) but does not in 7.1.3

Any update on this issue? Testing in .net 6 and the latest preview (7.2.0) of the SDK.

Any updates? Can’t PS remote from Azure Function (C#, net6) even when EnableUnsafeBinaryFormatterSerialization is enabled in project
