Updating "Person or Group" field of file getting uploaded via Powershell


  • Greetings,

    I am a complete programming/powershell noob.

    I grabbed parts from various scripts to create a powershell script that does the following after I provide the first and last name of a new employee:

    1. creates a folder in format "lastname, firstname" within a subfolder of a document library and stops inheriting permissions.

    2. Creates a folder called "2017" within.

    3.uploads 3 files to the "2017" folder.

    4. in the upload loop for each of the three files, it sets a metadata column called "Status" to "Not started"  

    Here is what I am missing. 

    1. I have an "employee" and "manager" column which both are of type "Person or Group".  Somehow it fails to update these two fields. Here is the code snippet:

    Foreach ($File in (dir $UploadSourceFolder -File))
        $FileCreationInfo = New-Object Microsoft.SharePoint.Client.FileCreationInformation
        $FileCreationInfo.Overwrite = $true
        $FileCreationInfo.Content = [System.IO.File]::ReadAllBytes($File.FullName)
        $FileCreationInfo.URL = $List.RootFolder.ServerRelativeUrl + "/" + $UploadTargetFolder + "/" + $File.Name
        $UploadFile = $List.RootFolder.Files.Add($FileCreationInfo)
        $UploadFile.ListItemAllFields["Status"] = "Started";
        $user = UserLookUp;
        $UploadFile.ListItemAllFields["Manager"] = $user;

    Here is the UserLookUp Function:

    Function UserLookUp()
    $Ctx = Get-Context -Url $Url -Username $Username -Password $Password
    $Web = $Ctx.Web
    Write-Host $Web.Title
    $User = $Web.EnsureUser("
    $userValue = new FieldUserValie
    Write-Host $User.Email

    This runs without error, but the "manager" field is empty when I check it in the browser.

    Any idea what I am doing wrong? 

    2. I was able to stop inheriting permissions for the "Last name, first name" folder, but now I need to add 2 groups and two single users with Full Control to that folder. 

    Any idea how to do that? 

    I know this is a lot and pardon my coding. This is my first attempt at writing a script.

    Any help is appreciated.
