Yes, you´re right. But that´s the issue in my case. It is not possible to show individually hidden/unhidden columns dependent from the respective user, which is defined by VBA "environ" for instance. E.g. Columns A, B and C are hidden. User A should only see column A. User B should only see column B and so on also when all 3 open the file at the same time. But reality is that all 3 see the same column. If only one person has opened the file then the "individual view" works.
