SharePoint Online PowerShell Tip: Conditional Scope – Binary Module

SharePoint Online PowerShell Tip to throw exception while connecting to Tenant.


Recently one of our customer requested us to share a code which should throw an exception while connecting to SharePoint Online if in case of credential invalid or not connecting to tenant site. Well, they have a binary module delivered by some suppliers which is pretty straight forward and simple. If all set to good code will execute if not exception thrown in other cmdlet. The module they use has bunch of cmdlets which are more or less mock up of SharePoint Online cmdlets. Connect-SPOService throws exception if credential are invalid and they need custom error message for the custom built cmdlet Connect-SPOTenant


  • Connect-SPOTenant : The sign-in name or password does not match one in the Microsoft account system
  • Connect-SPOTenant : Current site is not a tenant administration site.

PowerShell Code

Below is the PowerShell code shared by our client.

function global:Connect-SPOSite {
 param (
 [Parameter(Mandatory=$true, ValueFromPipeline=$true, Position=0)]
 begin {
 [System.Reflection.Assembly]::LoadFile("C:\Program Files\SharePoint Online Management Shell\Microsoft.Online.SharePoint.PowerShell\Microsoft.SharePoint.Client.dll") | Out-Null
 [System.Reflection.Assembly]::LoadFile("C:\Program Files\SharePoint Online Management Shell\Microsoft.Online.SharePoint.PowerShell\Microsoft.SharePoint.Client.Runtime.dll") | Out-Null
 process {
 if ($global:spoCred -eq $null) {
 $cred = Get-Credential -Message "Enter your credentials for SharePoint Online:"
 $global:spoCred = New-Object Microsoft.SharePoint.Client.SharePointOnlineCredentials($cred.UserName, $cred.Password)
 $ctx = New-Object Microsoft.SharePoint.Client.ClientContext $Url
 $ctx.Credentials = $spoCred
 if (!$ctx.ServerObjectIsNull.Value) {
 Write-Host "Connected to site: '$Url'" -ForegroundColor Green
 return $ctx
 end {


Indeed, the above code will not throw any exception because the ClientContext Object is instantiated and will not validate the credential but returns the ClientContext Object as output. More over Microsoft.SharePoint.Client.ClientContext doesn’t have ServerObjectIsNull property. No matter we supply wrong password the host shows Connected to Site!

Conditional Scope

C# code with conditional scope is below. This is just a demo so we haven’t used any scope methods or properties

using System;
using System.Management.Automation;
using Microsoft.SharePoint.Client;
using Microsoft.Online.SharePoint.TenantAdministration;
namespace xSharePointOnline
 [Cmdlet(VerbsCommunications.Connect, "SPOTenant")]
 public class ConnectSPOTenant : PSCmdlet
 public Uri SPOUrl;
 public PSCredential SPOCredential;
 protected override void ProcessRecord()
 using (ClientContext SPOClientContext = new ClientContext(SPOUrl))
 SPOClientContext.Credentials = new SharePointOnlineCredentials(SPOCredential.UserName, SPOCredential.Password);
 Tenant oTenant = new Tenant(SPOClientContext);
 ConditionalScope Scope = new ConditionalScope(SPOClientContext, () => oTenant.ServerObjectIsNull.Value != true);
