Sometimes it is necessary to hide a button in the ribbon of SharePoint. With the Office 365 PnP PowerShell extensions this task could be done very easy. In this example, we will hide the “Publish” button in the ribbon for a document library.

First, we need the ID/location of the element in the ribbon. This is the difficult part in the whole task. In most cases, we can find this element with the developer tools of the browser.

In our case the ID/location of the button is “Ribbon.Documents.Workflow.Publish”.

Next we need an xml file that will be used in the cmdlet from the PnP PowerShell extensions. In this simple xml file we need the ID/location, we found using the developer tools:

<CommandUIExtension>
    <CommandUIDefinitions>
        <CommandUIDefinition Location="Ribbon.Documents.Workflow.Publish" />
    </CommandUIDefinitions>
</CommandUIExtension> 

Last but not least, we can run the Set-SPOCustomAction cmdlet from the PnP PowerShell extensions:


$fileContent = Get-Content ".\DisablePublish.xml"
$fileContentAsString = [string]$fileContent

Add-SPOCustomAction -Name "DisablePublish" -Title "DisablePublish" -Description "-" -Group "a" -Location "CommandUI.Ribbon" -RegistrationType List -Sequence 10000 -RegistrationId 101 -CommandUIExtension $fileContentAsString

And that is the result:

To make the button visible again, use the cmdlet Remove-SPOCustomAction from the PnP PowerShell extensions. First, run Get-SPOCustomAction, to get the ID of the custom action, then run Remove-SPOCustomAction with this ID.
