I cant seem to get my CSOM powershell to work with SharePoint Online any more, everything I try to initialise tells me it hasnt been requested?

Connect-SPOSite (Personal Module)

$location = "C:\Users\colin.cook\Dropbox\FluidSharePoint\Scripts\SharePointOnline\Lib"
    $files =  get-childItem -LiteralPath $location | select Name
    $files | % {
        $file = $location + "\" + $_.Name
        [System.Reflection.Assembly]::LoadFile("$file") | out-null  

function global:Connect-SPOSite { 
param ( 
    [Parameter(Mandatory=$true, ValueFromPipeline=$true, Position=0)]

begin {


process {         
    if ($global:spoCred -eq $null) { 
        $cred = Get-Credential -Message "Enter your credentials to log into SharePoint Online:" 
        $global:spoCred = New-Object Microsoft.SharePoint.Client.SharePointOnlineCredentials($cred.UserName, $cred.Password) 

    $context = New-Object Microsoft.SharePoint.Client.ClientContext $Url 
    $context.Credentials = $spoCred 

    if (!$context.ServerObjectIsNull.Value) { 
        Write-Host "Connected to site: '$Url'" -ForegroundColor Green 
    return $context 
} end { 



PS C:\Windows\system32> $ctx = Connect-SPOSite "*****"

  • Did you ever get this working? I'm having the same issue – Axemasta Nov 21 '18 at 10:21

PowerShell is trying to access all properties and also tries to enumerate some colletions of $web (which have not been loaded - this is where your error occurs...).

Try not to "dump" everything. Try $Web.Title instead.


In order to use CSOM within your PowerShell scripts, you first need to download the Office Developer Tools based on your visual studio version.This package contains the client DLLs components for SharePoint Online.

Add-Type -Path "C:\Program Files\Common Files\microsoft shared\SharePoint Client\Microsoft.SharePoint.Client.dll" 
    Add-Type -Path "C:\Program Files\Common Files\microsoft shared\SharePoint Client\Microsoft.SharePoint.Client.Runtime.dll"

$Ctx = New-Object Microsoft.SharePoint.Client.ClientContext("SharePointSiteURL")

$Web = $Ctx.Web

Or load assembly file like this



$ctx = New-Object Microsoft.SharePoint.Client.ClientContext("SharePointSiteURL")
  • Thanks, I already load everything and make the connection separately in a module, the $ctx is a return of that which you can see above when I query $ctx but then when I try and initiate anything beyond that it seems to go and do some work but then I get the error shown in my question, I will edit my answer with the connection module. – Col.Cook Aug 15 '16 at 2:29
