If you already have the outline 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
End With
End Sub

It needs to be reset each time you open the workbook. (excel doesn't remember
it after closing the workbook.)

Hy!

I have grouped four rows in my excel sheet. Then I protect the sheet. When I
click on the "-"sign to hide the rows, I get the error message, that this is
not possible in protected sheets. I have written a lot of code, which is
based on protecting and unprotecting my sheets. I also need the grouping
function. Does anybody knows, how I can handle this problem? Is there a
possibilty to allow this function in protected sheets? Are there other
possibilities for the grouping function?
I thank you a lot for any help.
