Hide Microsoft Flow “Flows” Button on SharePoint Libraries/Lists

Microsoft Flow is a very useful integration tool released by Microsoft in Office 365. But in most of the cases, it started rolling out to all Office 365 users and started to show the Flow button in all SharePoint Lists/Libraries where modern experiences where activated. In some cases, IT would like to hide this option, in order to prevent parallel apps or flows from being developed outside IT.

How can we do this?

There is no Out-of the box way to disable Microsoft Flow from SharePoint sites via a browser. But you can achieve this via PowerShell + CSOM.

First of all, you’ll need to have the latest version of SharePoint Client Components installed, so that PowerShell can use the latest SharePoint Online client object model DLL’s.

Here’s the full working PowerShell Script (or if you prefer, take a look at my post on Technet):

[System.Reflection.Assembly]::LoadWithPartialName("Microsoft.SharePoint.Client") | Out-Null 
[System.Reflection.Assembly]::LoadWithPartialName("Microsoft.SharePoint.Client.Runtime") | Out-Null

$subwebcheck = Read-Host -Prompt "Do you want to process subsites? (enter 'Y' if yes)" 
 
# Generate ClientContext(ctx) function so we can reuse

     return $ctx 
}

        $childWebs = $rootWeb.Webs 
        $ctx.Load($rootWeb) 
        $ctx.Load($childWebs) 
        $ctx.ExecuteQuery() 
 
        # Perform update for all template types except APPs to disable Microsoft Flow Button 
        if($rootWeb.WebTemplate -ne "APP"){ 
            Write-Host $rootWeb.Url "is being updated to disable Microsoft Flow button"

        foreach ($childWeb in $childWebs) 
        {            
            processsubsites $childWeb.url 
        } 
}
