If you already have the outline/subtotals/autofilter applied, you can protect
the worksheet in code (auto_open/workbook_open??).

Option Explicit
Sub auto_open()
With Worksheets("sheet1")
.Protect Password:="hi", userinterfaceonly:=True
.EnableOutlining = True
'.EnableAutoFilter = True
'If .FilterMode Then
' .ShowAllData
'End If
End With
End Sub

It needs to be reset each time you open the workbook. (Earlier versions of
excel don't remember it after closing the workbook. IIRC, xl2002+ will remember
the allow autofilter setting under tools|Protection|protect sheet, but that
won't help when you're filtering via code.)

I want to protect the cells in my worksheet, but when I do I am no longer
able to collapse or expand grouped items (rows/columns). Any ideas on how to
protect my formulas but not disable grouping functionality?
