Retain Use Of Group/Outline On Protected Sheets/Worksheets

I have a sheet that I protect but i use the below code so that I can still use my gouping '+' or '-' symbols to hide/unhide rows.

ws.Protect Password:="PASSWORD", userinterfaceonly:=True
ws.EnableOutlining = True

This is ok but When close the workbook and reopen it, my sheet becomes fully protected and i cant use the group icons. Can anyone either suggest better code or a way to initilise the workbook to act in this way when it loads up. For Reference Below is my full

Sub ProtectAll()
Dim ws As Worksheet
sSheet = Control.Name
For Each ws In ThisWorkbook.Worksheets
Select Case ws.Name
Case sSheet1
Case Else
ws.Protect Password:="PASSWORD", userinterfaceonly:=True
ws.EnableOutlining = True
End Select
Next ws
End Sub
