Hi @Dhamley ,

There is no direct tenant settings to remove Sync icon from all sites or newly created site. You could use CSOM PowerShell to solve it.

PowerShell commands:

#Load SharePoint CSOM Assemblies  
Add-Type -Path "C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\16\ISAPI\Microsoft.SharePoint.Client.dll"  
Add-Type -Path "C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\16\ISAPI\Microsoft.SharePoint.Client.Runtime.dll"  
  
Function Disable-SPOSyncButton([String]$SiteURL)  
{   
    Try{  
        #Setup the context  
        $Ctx = New-Object Microsoft.SharePoint.Client.ClientContext($SiteURL)  
        $Ctx.Credentials = $Credentials  
   
        #Get the Web and Sub Sites  
        $Web = $Ctx.Web  
        $Ctx.Load($Web)  
        $Ctx.Load($Web.Webs)  
        $Ctx.ExecuteQuery()  
   
        $Web.ExcludeFromOfflineClient=$true  
        $Web.Update()  
        $Ctx.ExecuteQuery()  
        Write-Host -f Green "Sync Button is Disabled for the Site:" $($SiteURL)  
   
        #Iterate through each subsite of the current web  
        ForEach ($Subweb in $Ctx.Web.Webs)  
        {  
            #Call the function recursively  
            Disable-SPOSyncButton -SiteURL $Subweb.url  
        }  
    }  
    Catch {  
        write-host -f Red "Error Disabling Sync Button!" $_.Exception.Message  
    }  
}  
   
#Set parameter values  
$SiteURL="https://crescent.sharepoint.com/"  
   
#Get Credentials to connect  
$Cred= Get-Credential  
$Credentials = New-Object Microsoft.SharePoint.Client.SharePointOnlineCredentials($Cred.Username, $Cred.Password)  
   
#Call the function  
Disable-SPOSyncButton -SiteURL $SiteURL

Hi @Jinwei Li-MSFT ,

I've tried using your solution but it just wont do it for all sites, it will only do it for the site url chosen:

Call the function

Disable-SPOSyncButton -SiteURL $SiteURL
cmdlet Get-Credential at command pipeline position 1
Supply values for the following parameters:
Sync Button is Disabled for the Site: https://contoso.sharepoint.com/

and then it stops, any idea ?

Thanks,
Adam
