Hello SharePointers,

Below are the CSOM script to set/populate People Picker value in a SharePoint list .

$userName = “domain\username”
$spuser = EnsureUser $context $userName
$lookupValue = @()
if($spuser -ne $null){
$spuserValue = New-Object Microsoft.SharePoint.Client.FieldUserValue
$spuserValue.LookupId = $spuser.id
$lookupValue += $spuserValue
}
$userValue = [Microsoft.SharePoint.Client.FieldUserValue[]]$lookupValue
$listItem[“Your People Picker FieldColumn name”] = $userValue
$listItem.Update()

Happy SharePointing Folks 🙂
