Set-PnPLabel doesn't appear to be working, am I wrong?

[AlanPS1]

Set-PnPlabel has the following description:

"Sets a retention label on the specified list or library"

Having authenticated to both SPO sites & OneDrive for Business sites I am trying to apply labels within document libraries but with no success. My authentication methods use both Global admin using MFA and a service principal configured with a self signed certificate. Connect-PnPOnline is used to connect.

I have pre-configured Labels and Policies so I would have expected the following 2 commands to apply the label after having successfully created some target folders using Add-PnPFolder, within OD4B & SPO Site.

Working well:

OD4B - Add-PnPFolder -Name "Test Folder 12345" -Folder "Documents"
SPO - Add-PnPFolder -Name "Test Folder 12345" -Folder "Shared Documents"

Not working:

OD4B - Set-PnPLabel -List "Documents/Test Folder 12345" -Label "Test"
SPO - Set-PnPLabel -List "Shared Documents/Test Folder 12345" -Label "Test"

I see other blogs and others online (not many though) indicating that they have these Cmdlets working. When I run these commands, even with the verbose switch I get no feedback so it looks to have applied. The label does not apply however.

This issue here may or may not be related but I thought I'd link it. I am not using the SyncToItems switch.

Can any other get success using Set-PnPLabel? Am I perhaps doing it wrong or are there issues that I am overlooking?

NB: Now I have noticed the labels applying and visible on files within folder. Is there a way to use PnP to set a label on a sub folder of Documents in OneDrive or a sub folder of Shared Documents in SharePoint Online?

Further details have been posted on this Github Issue.

Thanks in advance.

Mostly, I was misinterpreting where I would see the label. The command is working and you can see it on the files within the folders so my mistake. I was looking at the folder itself which doesn't show the label.

I can't however use Set-PnPLabel to target any folders within the root of Documents or Shared Documents. Is anyone aware of a way to uses PnP to set a label on a folder within a library please?

Further details have been posted on this Github Issue.

I am attempting the below method ...

$WD = (Get-PnPListItem -List Documents | Where {$_.FieldValues.Title -eq "My Working Documents" }).Id
Set-PnPListItem -List "Dcocuments" -Identity $WD -Label "WorkingDocs"

This again doesn't seem to set a label on the folder in a way that would allow the contents of the folder to have a diferent label from the root "Documents" or "Shared Documents" folder.

Ok, so I have it working.

NB This assumes you have created & published the required retention labels @ https://compliance.microsoft.com/recordsmanagement. "Default" & "SharedDocs" in this example.
NB: This is targeting OneDrive but can be easily adapted to suit SharePoint Online.

$SiteUrl = "https://<tenant>-my.sharepoint.com/personal/john_doe_<domain>_co_uk"

Connect-PnPOnline -Url SiteUrl

$Context = New-Object Microsoft.SharePoint.Client.ClientContext($SiteUrl)
$web = $Context.Web
$Context.Load($Web)

Set-PnPLabel -List "Documents" -Label "Default"
Write-Verbose "Label called 'Default' applied to 'Documents - Root' Folder"

Add-PnPFolder -Name "My Shared Documents" -Folder "Documents"

$Folder = Get-PnPFolder -Url "Documents/My Shared Documents"
$Folder.ListItemAllFields.SetComplianceTagWithNoHold("SharedDocs")
Invoke-PnPQuery

Write-Verbose "Label called 'SharedDocs' applied to 'My Shared Documents' Folder"
