Re: RESOLVED: How to change Modern page Author from the "Created By" field to something else

Dear Vesa,

I tried to follow your recommendation via the script I wrote:

[string]$SitePagesURL ="https://tenant.sharepoint.com/sites/SiteCollectionurl/subsite/"
[string]$PageLibPublicName = "Site Pages"

[int]$TempUserID = 0

function Load-DLLandAssemblies
{
	[string]$defaultDLLPath = ""
	# Load assemblies to PowerShell session 
	$defaultDLLPath = "C:\Program Files\SharePoint Online Management Shell\Microsoft.Online.SharePoint.PowerShell\Microsoft.SharePoint.Client.dll"
	[System.Reflection.Assembly]::LoadFile($defaultDLLPath)
	$defaultDLLPath = "C:\Program Files\SharePoint Online Management Shell\Microsoft.Online.SharePoint.PowerShell\Microsoft.SharePoint.Client.Runtime.dll"
	[System.Reflection.Assembly]::LoadFile($defaultDLLPath)
	$defaultDLLPath = "C:\Program Files\SharePoint Online Management Shell\Microsoft.Online.SharePoint.PowerShell\Microsoft.Online.SharePoint.Client.Tenant.dll"
	[System.Reflection.Assembly]::LoadFile($defaultDLLPath)
}
Load-DLLandAssemblies

#get and save your O365 credentials
[string]$username = "AdminLogin@tenant.onmicrosoft.com"
[string]$PwdTXTPath = "C:\SECUREDPWD\ExportedPWD-$($username).txt"
$secureStringPwd = ConvertTo-SecureString -string (Get-Content $PwdTXTPath)
$cred = New-Object System.Management.Automation.PSCredential -ArgumentList $username, $secureStringPwd

# ---------------------------------------------------------------------------------------------------------------
#connect to the web site using the stored credentials
Write-host " "
Write-host " -------------------------------------------------------------------------------------------- " -ForegroundColor green
Write-host " ---- CONNECT THE SITE --- " -ForegroundColor green
Write-host "   CONNECTED SITE:", $SitePagesURL  -ForegroundColor Yellow

$Myctx = New-Object Microsoft.SharePoint.Client.ClientContext($SitePagesURL)

$Myctx.Credentials = New-Object Microsoft.SharePoint.Client.SharePointOnlineCredentials($cred.UserName,$cred.Password)
$Myctx.RequestTimeout = 1000000 # milliseconds
$MyspoRootweb = $Myctx.Web
$Myctx.Load($MyspoRootweb)
$Myctx.ExecuteQuery()

Write-Host " "
Write-Host " ---------------------------------------------------------"
Write-Host "  >>>> # Server Version:" $Myctx.ServerVersion " # <<<<<<" -ForegroundColor Green 
Write-Host " ---------------------------------------------------------"
Write-Host " "

Write-host " -------------------------------------------------------- "
Write-host "   -->> RootSite:", $MyspoRootweb.URL -ForegroundColor green

Write-host " "

$Alllists = $MyspoRootweb.Lists
$MyPagelist = $Alllists.GetByTitle($PageLibPublicName)

$MyPagelistItems = $MyPagelist.GetItems([Microsoft.SharePoint.Client.CamlQuery]::CreateAllItemsQuery())
$Myctx.load($MyPagelistItems)
$Myctx.executeQuery()

foreach($PageItem in $MyPagelistItems)
{
	Write-Host "ID:", $PageItem["ID"], " - Title:", $PageItem["Title"]
	$ModifiedByuser = $PageItem["Editor"]
	$CreatedByuser = $PageItem["Author"]
	if ($ModifiedByuser.LookupId -eq $CreatedByuser.LookupId)
	{
		Write-Host "       ===> Modified by: ", $ModifiedByuser.LookupValue, "[", $ModifiedByuser.LookupId, "] - Created by:", $CreatedByuser.LookupValue, "[", $CreatedByuser.LookupId, "]" -ForegroundColor Yellow
	}
	else
	{
		$TempUserID = $ModifiedByuser.LookupId
		Write-Host "       ===> Modified by: ", $ModifiedByuser.LookupValue, "[", $ModifiedByuser.LookupId, "] - Created by:", $CreatedByuser.LookupValue, "[", $CreatedByuser.LookupId, "]" -ForegroundColor Red

		$PageItem["Author"] = $TempUserID
		$PageItem.Update();
		$Myctx.ExecuteQuery();
	}
}  

But nothing change at the "Created by" level, the change is apply for the "modified by" with my admin account used for that script execution.

So my issue is not solved and i'm showing only the script execution account as news publisher.

Thanks for your help if you have another way.
